• Laptop Randomly Turning On and Off

  - by Ian Mallett

  So, I have a pretty new laptop, and one of its quirks is that, at random times (though typically in the middle of the night), it seems to wake up from sleep mode, churn a bit, and then go back into sleep mode. I write "seems" because its fans are very loud, so it's obvious when it's not asleep, but during the time it is "on", I can't see anything on the screen. I have researched the problem somewhat, and could only find similar issues; nothing identical. In those cases, it appeared that certain devices could be responsible. Nothing is plugged into my computer during this behavior, but I nonetheless disabled every device's permission to wake the computer through the device manager. This included disabling the magic packet wake for the network (despite its only having a wireless connection). Using "powercfg /lastwake" gives an empty wake history. But, I also went through all the tasks and checked if they would wake the computer. None appeared to. The problem persisted, so, after some more research, I found this, and executed it for all power schemes on the computer. The problem persists.

• Why does my exchange message filtering rule not work?

  - by Jon Cage

  I have two rules set up to sort incoming bug reports. The first is specific to a single device: Apply this rule after the message arrives sent to SMS Distribution and with <source_device_number>: in the body move it to the BugReports\<source_device_number> folder ..and the second is a catch-all for everything else: Apply this rule after the message arrives sent to SMS Distribution move it to the BugReports folder For some reason though, the first rule never seems to act even though it's higher in the list. So for some reason an email like the following doesn't seem to get caught by the first rule: From: <SourceDeviceUID> To: SMS Distributor Subject: Message from <SourceDeviceUID> Message: <source_device_number>: Device encountered a problem. Details below... ...where <source_device_number> is an integer. The second rule works fine. But for some high-priority devices, I want them automatically sorted. Why might that first rule fail?

• Can any iSCSI NAS appliance replicate / clone a LUN to an external drive?

  - by Boden

  I would like to backup using Windows Imaging to some kind of NAS appliance. I believe this will require the NAS to support iSCSI. I would then like the appliance to support the replication of the iSCSI LUN to an external eSATA or USB disk connected directly to the appliance. I've found plenty of NAS appliances that can do iSCSI and replicate to an external drive, but none that I've found thus far can do both at once. That is, the devices can do iSCSI, but then the replication feature doesn't work. The idea here is to backup to an appliance located in a secure office far away from the server room. Offsite backups to external hard drive could be managed from the appliance. The benefits of such a setup would be: 1) very unlikely that fire or random theft would affect both server-room backup and "remote" backup appliance 2) offsite backups could be managed by multiple trusted people without granting access to server room 3) Windows imaging provides poor man's deduplication, so each backup volume can contain a decent backup history. I understand why this would be a non-trivial thing to implement, but I'm wondering if such a thing exists? Preferably a tabletop, low to medium cost device. Alternative solutions welcome. NOTE: I'm backing up very few but very large files, so file replication is not a good option.

• Dell Driver Support for Latitude E6320 Windows 7 Enterprise

  - by IamPolaris

  I recently did a reinstall of Windows 7 Enterprise on a Dell Latitude E6320, which is a 64 bit system. After the install process, and doing typical Windows Update stuff, I looked at my Device Manager and found that I had devices which were missing drivers. My missing drivers: After going to the Dell Support site and looking at the files, and doing some sleuthing I found the following support document: http://downloads.dell.com/utility/Latitude%20E-Family%20%20Mobile%20Precision%20Re-Image%20How-To%20Guide%20-%20A03%20Rev%203%200.pdf This document hints in appendix C that the Broadcom USH is the Control Point Security and the Unknown device is Micro freefall sensor. The network controller is my wireless, as I cannot connect wirelessly, and the final missing driver I am not sure. Attempting to install the control point security exe on the support page will not work. After downloading, I am given the message that I am attempting to install a 32 bit driver on a 64 bit machine EVEN THOUGH I selected the win7 64 bit option from the support page. Beyond that, some of the drivers (Which are confusing to read and hard to understand what they do) and the system utilities which are supposedly supposed to make this process simpler will either a) not run because they are 32 bit exe's or b) the support page cannot find the file attempted to download. Is there anything I can do to get (at the very least) my wireless running, but idealistically all of my drivers. A solution which assumes Dell is completely incompetent would be ideal. :P Some forums have said that I should download the chipset driver, others say to get the system utility file (DSS_UTIL_WIN_R282536.EXE). I have had no luck as of yet...

• Converting software RAID1 to RAID10 for /boot

  - by luckytaxi

  Array info: /dev/md0 - /dev/sda1 and /dev/sdb1 /dev/md2 - /dev/sda2 and /dev/sdb2 Partition info: /boot - /dev/md0 / - /dev/md1 I have two drives that are setup as RAID1 using software RAID on Redhat. I added two additional drives (same size) and I would like to conver the RAID1 to a RAID10. The problem I'm having is adding the last drive to the array. I've gotten as far as creating a RAID10 with two missing devices but as soon as I add the last drive, all hell breaks loose. It seems /dev/sda1 is the culprit. What I'm not too sure about is how to create the RAID10. I've tried the following mdadm --create /dev/md2 --level=raid10 --raid-device=4 /dev/sdc1 missing /dev/sdd1 missing I then proceeded to fail /dev/sdb1 from /dev/md0 and added that partition to /dev/md2. I proceeded to install the MBR on EACH partition since boot resides on /dev/sdx1 on each drive. As a test, all is well, I'm able to boot back into the system once I do a quick reboot. Now, when I go add the last drive /dev/sda1, it breaks. I attempted to install grub on /dev/sda1 and I get the following ... grub> root (hd0,0) /dev/sda root (hd0,0) /dev/sda Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0) setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 2: Bad file or directory type At this point, the array is hosed I believe. I rebooted the server and it refuses to boot.

• Trying to limit IMAP folders/mailboxes my iPhone/iPad sees

  - by QuantumMechanic

  (Note: I am using dovecot 1.0.10 on Ubuntu 8.04.4 LTS. Yes, I know I need to upgrade before next year :) (Note: The SMTP/IMAP server in question only serves my family, so there's only a very few users. Certainly what I propose below, even it it works, would be a logistical nightmare with any significant number of users). I have noticed (and have confirmed via google) that the iOS mail app is terrible in its handling of IMAP subscriptions, namespaces, etc. For example, my iPhone and iPad will see EVERYTHING (all mailboxes, folders, etc.), whereas clients like Thunderbird, alpine, etc. only see what I tell them to see. This makes it an incredible pain to move mail between mailboxes because I have to scroll through a gazillion things. The mail_location in dovecot.conf is: mail_location = mbox:%h/Mail/:INBOX=/var/mail/%u To get around this, I've been considering doing the following for user foo: Create a dovecot userdb with a foo-ios virtual user in it, whose UID is identical to that of the real (in /etc/passwd) foo user and with a homedir of /home/foo-ios. ln -s /var/mail/foo /var/mail/foo-ios mkdir -p /home/foo-ios/Mail cd /home/foo-ios/Mail ln -s /home/foo/Mail/mailbox-i-want-visible mailbox-i-want-visible Make symlinks for the rest of limited set of mailboxes/folders I want visible to the iOS mail app. chown -R foo:foo /home/foo-ios Change iOS mail app settings to log in as user foo-ios instead of user foo. Will this work or will there be some index/file corruption hell because there will be two sets of indexes (one set living in /home/foo/Mail/.imap and other set living in /home/foo-ios/Mail/.imap) indexing the same underlying mbox files? And I'd be more than happy to hear of a better way to do this with dovecot! (Or to hear that dovecot 2.x works better with iOS devices).

• External SATA drive does not work without the optional USB cable *also* connected

  - by Software Monkey

  I have Vantec NST-260SU external eSATA/USB drive enclosure (which came with an optional separate power supply) connected to a relatively new Windows 7 computer. The drive should work as a SATA drive with either the separate power supply or using a USB cable solely for power. I would prefer to use the external power supply because I have used all my rear USB ports. Now, if I connect both the eSATA and USB cable, then: The drive shows in the BIOS list of AHCI drives (and not in the list of attached USB devices). Everything I can see about it in Computer Management seems to show it as a SATA driver (for example, it shows as "Location 0 (Channel 5, Target 0, Lun 0)" like my other SATA drives (and not "on USB Mass Storage Device" like my USB flash-drives). It seems very fast, very much faster than my USB flash drives. However, if I disconnect the USB cable and attach the power adapter instead, the drive does not show in the BIOS list and cannot be seen by Windows. The power LED on the enclosure is lit, and the drive enclosure becomes warm after running for a bit, so I am sure it is receiving power. Does anyone know if this device requires both the USB and eSATA cable, and if so, why? Or is there possibly something I need to do to reset the enclosure to not need the USB - the install instructions are pretty clear that you must connect the SATA cable before connecting the USB cable in order for the drive to function as SATA, which I am sure I did. PS: I have reviewed the small manual which came with it, which has not been of help.

• WRT54GL Tomato Router in Client wireless mode to an iPhone Personal Hotspot

  - by Gordo

  I am trying to connect a router with Tomato firmware to an iPhone 4. The goal is to connect to the Personal Hotspot in Client Wireless mode. This should allow wired and wireless users to connect to the router rather then the iPhone. In theory this should be possible but I am having difficulty. Router Linksys WRT54GL Tomato 1.28.1816 firmware iPhone iPhone 4 iOS 5.1 (9B176) Carrier Rogers Wireless Personal Hotspot works with other devices, wifi/bluetooth/usb iPhone Personal Hotspot settings Mode: B/G Security: WPA or WPA2 Personal Encryption: AES Router IP: 172.20.10.1 Subnet: 172.20.10.0 Min IP: 172.20.10.2 Max IP: 172.20.10.14 maximum number of wireless tethered hosts is 5 I have followed the directions here: http://www.wi-fiplanet.com/tutorials/article.php/3810281 Ensured that the router subnet does not 'collide' with the iPhone subnet. Here is the configuration of the Tomato 'Basic - Network - Wireless' section: http://i.stack.imgur.com/pbmTB.png I have tried several variations of this configuration, but nothing seems to work. NOTE: I have successfully connected to my own wifi network in Wireless Client mode, so I am confident that there are no bad cables or other hardware issues. I would prefer to use Tomato, but DD-WRT maybe my only other option. Thanks!

• How ZFS handles online replacement in a RAID-Z (theoretical)

  - by Kevin

  This is a somewhat theoretical question about ZFS and RAID-Z. I'll use a three disk single-parity array as an example for clarity, but the problem can be extended to any number of disks and any parity. Suppose we have disks A, B, and C in the pool, and that it is clean. Suppose now that we physically add disk D with the intention of replacing disk C, and that disk C is still functioning correctly and is only being replaced out of preventive maintenance. Some admins might just yank C and install D, which is a little more organized as devices need not change IDs - however this does leave the array degraded temporarily and so for this example suppose we install D without offlining or removing C. Solaris docs indicate that we can replace a disk without first offlining it, using a command such as: zpool replace pool C D This should cause a resilvering onto D. Let us say that resilvering proceeds "downwards" along a "cursor." (I don't know the actual terminology used in the internal implementation.) Suppose now that midways through the resilvering, disk A fails. In theory, this should be recoverable, as above the cursor B and D contain sufficient parity and below the cursor B and C contain sufficient parity. However, whether or not this is actually recoverable depnds upon internal design decisions in ZFS which I am not aware of (and which the manual doesn't say in certain terms). If ZFS continues to send writes to C below the cursor, then we are fine. If, however, ZFS internally treats C as though it were gone, resilvering D only from parity between A and B and only writing A and B below the cursor, then we're toast. Some experimenting could answer this question but I was hoping maybe someone on here already knows which way ZFS handles this situation. Thank you in advance for any insight!

• kvm-over-ip, multiple machines per cable run

  - by Sirex

  I'm looking at getting a kvm-over-ip setup for a server room. Typically these devices have 16 or so cat5 leads that come out of them and then a convertor that converts each cat5 into a vga & ps2 pair. Can you run one cable from the unit into a switch, and then leads from the switch into each machine ? I have several machines on the other side of the server room that i'd like to have avaliable but i dont want to run 16 cables to them. I'm thinking this should be possible being IP layer and all, but as each device normally has its own cable out the back of the kvm unit i'm not certain. Perhaps the kvm's rear ports act essentially like a switch anyway in which case it should work, or perhaps if i run all 16 cables into a seperate switch right next to it and aggregate the ports together, run one cable to a switch on the other side of the room with similar number of ports agregated together, then use that switch to plug each macine into ? I'm fairly sure this is possible, but i just want to check before i shell out the cash as i've never tried it.

• OpenVZ with bridged interfaces and VLAN

  - by Deimosfr

  Hi, I've got a problem with OpenVZ with bridged VLAN. Here is my configuration: +------+ +-------+ +-----------+ +---------+ br0 |VE101 | | | | OpenBSD |----->| Debian |------->| | | WAN |--->| Router | | OpenVZ | +------+ | | | Firewall |----->| br0 br1 | br1 +------+ +-------+ +-----------+ +---------+------->|VE102 | |br0 | | |VLAN br0.110 +------+ v +---------+ |VE103.110| +---------+ I can't make VLAN work on br0 (br0.110) and I would like to understand why. I don't have any switch so no problem with unmanageable switch. I've configured a VLAN interface on OpenBSD in /etc/hostname.vlan110: inet 192.168.110.254 255.255.255.0 NONE vlan 110 vlandev sis1 And it seems to be working fine. I've also adapted my PF configuration to work with VLAN but I don't see any incoming traffic. On my Debian Lenny, here is my interfaces configuration : # The loopback network interface auto lo iface lo inet loopback # br0 auto br0 iface br0 inet static address 192.168.100.1 netmask 255.255.255.0 gateway 192.168.100.254 network 192.168.100.0 broadcast 192.168.100.255 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off # VLAN 110 auto br0.110 iface br0.110 inet static address 192.168.110.1 netmask 255.255.255.0 network 192.168.110.0 gateway 192.168.110.254 broadcast 192.168.110.255 pre-up vconfig add br0 110 post-down vconfig rem br0.110 It looks OK, but when I start my VE, here is the message: ...

• Win Svr 2003 DHCP Bad Addresses

  - by VinceM

  After looking at other posts I still can figure this out. I'll start at the beginning... I inherited this network and I'm not the most knowledgeable about networking... We have a AD DHCP Server that is also our DNS server, We were having some VPN issues (on the same server) and my boss decided to disable routing and remote access, which cleared the settings. We couldn't get it set back up correctly so we rolled back to a backup drive they created a number of months ago. Since rolling back I've had Bad_Address listings in DHCP and there is a number of duplicate records in the DNS Forward Lookup Zones. We have less than 50 devices on the network but I have over 90 Bad Addresses showing. This server is currently running but we get IP address conflicts all the time on pretty much all the computers. I have had people do release and renew but it didn't help... I have also deleted and re-added the scope to no avail either. Any help or ideas would be greatly appreciated and I apologize if I missed another post that has information to help. Thanks, Vince

• How to configure a Linux kernel based on the modules currently in use?

  - by Carla

  Hello, I'm willing to build a minimal kernel with only the needed things for my machine; so I started by compiling the kernel from the ground up, using the default configuration and adding things that I know for sure I have (i.e.: Ethernet card, WiFi card, ...). But there are several other things not so easy to know about (i.e.: the watchdog timer) so I came across AutoKernConf which supposedly detects the hardware of the machine and generates a kernel configuration file with the settings for the found devices. The problem is it contained several settings repeated and even some which I don't have (I'm using a Dell laptop and one of the things it "found" was something of a Toshiba one). So I ended up building a kernel with the configuration that came out of the make allmodconfig command, which is a kernel with most of the things compiled as modules. Booting into that kernel and running lsmod I can see all of the kernel modules in use (the ones really needed) and I would like to know if there is a tool or some way for me to parse that list and convert it to the corresponding kernel configuration file. Or how to map each one with the appropriate options in the kernel so that I can manually set them. Thank you very much for your time.

• Linux wireless disconnect every 20 minutes

  - by james

  My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!

• Is there a historical computer peripherals or accessories museum or even just a current list?

  - by zimmer62

  Thinking about all the unique and different peripherals I've owned over the years, from ISA capture cards, to parallel port controlled shutter glasses for 3d games. I've seen many many accessory or computer peripherals come and go. The nostalgia of these things is a lot of fun. I tried to find some sort of historical time-line or list but what mostly turned up is computers themselves. I'm more interested in the mice, scanners, the weird adapters that shouldn't exist, short run very rare products, strange devices from computer shows in the 80's and 90's... Hardware you might find in a geeks basement that would be completely useless now, but was the coolest thing around when it was new. An example would be a drawing tablet I had for my TI-99 computer, or the audio tape player accessory for a C64 which let you save files to audio tapes, An ISA card that did the same for PC's hooked up to a VCR. Remember that IBM-PC Jr upgrade kit, that added a floppy drive, more memory and the AT switch in the back? I'd love to find either a wiki, or a list that has already been assembled which contain many of these weird (or common) accessories. I've had so many over the years I suppose I could start a wiki here if such a list doesn't already exist.

• Why does my Belkin Play router regularly stop working for a few minutes at a time?

  - by YeahStu

  I recently purchased a Belking Play dual-band router for my home. About every few hours, the router stops working or "cuts out" for several minutes before coming back online automatically. My old one did this as well. I figured out a main problem was my wireless home phone, which sends a 2.4GHz signal. Anytime someone would call the phone, my router would get interrupted. Therefore, I unplugged this phone and got a wired phone. Unfortunately, my wired phone has the same problem. Therefore, I unplugged the wired phone. Unfortunately, my router still has regular issues. I live in a home with neighbors within close proximity to me, so it might be possible that their devices are the ones causing me problems. How can I determine what is causing my router problems? I thought that the point of a dual-band router was that if a signal was interfering on one band then it would be uninterrupted on another. However, it seems that is not the case. Does anyone have any tips on how to troubleshoot this or any knowledge you can share to properly set my expectations?

• Why does my Intel Tolapai network chip not transmit packets?

  - by Hanno Fietz

  I'm trying to deploy an embedded system (NISE 110 by Nexcom) based on the Intel EP80579 (Tolapai) chip. Tolapai apparently integrates controllers for Ethernet etc. on a single chip (Intel homepage). The machine can't get a network connection. Diagnosis as far as I could manage: Drivers drivers from Intel compiled and installed without problems (version 1.0.3-144). Kernel version and Linux distribution (CentOS 5.2, 2.6.18) match the driver's installation instructions. drivers are loaded and show up in lsmod (module names are gcu and iegbe) interfaces eth0 and eth1 show up in ifconfig ifconfig I can bring up the interfaces with fixed IP pinging the interface locally works ifconfig shows flag UP but not RUNNING Link ethtool shows "Link detected: no", "Speed: unknown (65536)" and "Duplex: unknown (255)" Link LED is on on the other side of the cable, ethtool shows "Link detected: yes" and reports a speed of 1000 Mbps, which has allegedly been auto-neogotiated with the problematic device. Network traffic analysis the device does not reply on ARP, ICMP echo or anything else (iptables is down) when trying to send ICMP or DHCP requests, they never reach the other end activity LED is off on the device, on at the other end. I tried the following without any effect: Different cables (2 straight, one crossed), I get the link LED lit up on each. Three different devices on the other end (one PC, one netbook, one router) Fixed ARP table entries on both sides Connecting both network ports of the machine with each other, won't ping through the cable, but will ping locally. Tried straight and crossed cables for that.

• Remote paging with Nagios when network is down and email won't work -- cellular modems and alternatives

  - by Quinten

  What is the best option for remote paging when network services are down? I'm looking for a solution that can let me know when network services are down during off-hours only, and especially when email/smtp services are out. Therefore, it needs to be redundant to our network and power supply. I'm imagining a cellular modem is one option. What's the price range for these? Is anybody using them and feel that they are worth the cost? I'm imagining that it's something we would end up sending an emergency page ~ 1x/month at most, so I'd like the pricing to reflect that--I don't mind a high per-page cost as long as it has a low recurring cost. Another option would be to expose at least one server to remote ping, and run a check script on a remote server. Are there paid options for this? Currently, we run Nagios on a Linux VM on a Windows 2008 Hyper-V host. It would be great if the solution would work in that environment, but I know it's tricky with external devices, and we could move Nagios to a standalone workstation if needed.

• How to increase the speed between two external hard drives on my laptop?

  - by Roman

  Hello, I own Sony Vaio Z laptop with two external USB ports. It's quite new and has USB 2.0 support. I'm using Vista x64 on it. I also have two external usb hard drives, Iomega 500GB and WD for 1TB. Every hard drive has USB 2.0 support. I connect two devices to my laptop and trying to copy date from one hard drive to another. But it takes a lot of time! The speed is about 15 Megabytes per second. I have to wait toooooo long to copy all the information from one hard drive to another. When I try to copy information from my internal (SSD) hard drive, it works fine for both external drives. The speed is very high and it shows me something about 100 Megabytes per second. It makes me feel that USB 2.0 is OK on both drives. But when I'm trying to copy from one external drive to another external, I still get very low speed. I checked out Device Manager and here is the settings I have: (sorry, can't upload image because of my rating, check this url: http://picbite.com/image/122073daljo/ ) I think it's because two of my external drives use the same USB 2.0 controller. Is there any way to make it work faster? Is it possible to move one of my USB ports to other USB 2.0 controller? Or is there any software which can help me to automate copying all the files thru my internal drive? I have only about 3 gigabytes free space on internal drive and it's quite difficult to move manually every file from one hard drive to internal and then again to another internal.

I also have two external usb hard drives, Iomega 500GB and WD for 1TB. Every hard drive has USB 2.0 support. I connect two devices to my laptop and trying to copy date from one hard drive to another. But it takes a lot of time! The speed is about 15 Megabytes per second. I have to wait toooooo long to copy all the information from one hard drive to another. When I try to copy information from my internal (SSD) hard drive, it works fine for both external drives. The speed is very high and it shows me something about 100 Megabytes per second. It makes me feel that USB 2.0 is OK on both drives. But when I'm trying to copy from one external drive to another external, I still get very low speed. I checked out Device Manager and here is the settings I have: (sorry, can't upload image because of my rating, check this url: http://picbite.com/image/122073daljo/ ) I think it's because two of my external drives use the same USB 2.0 controller. Is there any way to make it work faster? Is it possible to move one of my USB ports to other USB 2.0 controller? Or is there any software which can help me to automate copying all the files thru my internal drive? I have only about 3 gigabytes free space on internal drive and it's quite difficult to move manually every file from one hard drive to internal and then again to another internal.

• How to determine the root cause of a system lockup on Ubuntu 8.04 LTS?

  - by jdt141

  I'm currently working a project that involves setting up a PC/104 stack and running Ubuntu 8.04 LTS. We need to use the PC/104 stack because its an embedded application - and we're required to use a DeviceNet peripheral card to communicate to other devices. (DeviceNet is just a protocol on top of CAN.) Anyway, the following hardware is on the stack: Kontron MOPSPM104 with a 1GHz Intel Celeron processor ConnectTech FlashDrive/104 4GB Industrial Temp (-40 to +85 C) Woodhead (Molex) PC104DVNIO DeviceNet card A run of the mill 104 power supply The Kontron Board offers two serial ports, one VGA out, and two USB ports. The DeviceNet card is an ISA card. Because of this (per the User's Guide for the Kontron Board), I have manually set the IRQs in the BIOS to be appropriately configured, and turned off ACPI in both the BIOS and passed the appropriate flag in GRUB. I've installed Ubuntu 8.04 desktop, 32 bit. The problem that I'm having is that, from time to time, the entire 104 stack locks up. This only seems to happen in two cases, both of which we're running GNOME. We have a custom application that uses the DeviceNet card, and the system will lock up, or (more frequently) when we're running Firefox and either surfing for some information or trying to test it - typically by streaming video from a IP-camera. The reason I ask this questions is I cannot determine the root cause of this lockup. The IRQs appear to correctly configured in the BIOS and as the Kernel sees them, and nothing is logged to dmesg. If you all could help me determine the root cause of this lockup, I would greatly appreciate it. Thanks.

• Windows 7 BSOD on startup

  - by Cristy

  I got a BSOD today after getting home from 11 hours of work... It seems to work in SAFE MODE (sometimes, not always) The BSOD says: SYSTEM_SERVICE_EXCEPTION STOP: 0x0000003b WimFsf.sys - Address FFFFF88001A6B76B base at FFFFF88001A600000, DateStamp 4a5bc362. Sometimes it shows the welcome screen, shows the destkop for a few seconds and then BSODs Already did: unplugged all the USB devices reset the CMOS I haven't installed any new software recently. What should I do? EDIT: I've managed to get into safe mode and it seems to works fine. When I go into normal mode it shows the desktop then it freezes... Is it more likely to be a software or hardware problem? EDIT2: I've managed to get into normal mode by disabling all the non-microsoft services & startup programs. One more thing: When I shut down my PC, on the "Logging off" screen appear some artifacts. I don't think it's because of my graphics card cause I've opened Black OPS and it worked fine. It's so strange... It still BSODS on startup (but there a ~=10% that it will not), and when it doesn't BSOD's it works fine...

• Is there a realiable way to troubleshoot wake up from sleep in Windows?

  - by Borek

  Is there a reliable way to troubleshoot laptop wakes? I've seen "heuristics" posted here and there but isn't there really a simple and deterministic way to tell what's causing a problem? Specifically, my laptop wakes up about every hour for about 2 minutes. Exported event log entries are here: http://www.mediafire.com/?abcqb00v5wyo6pj. I've tried: powercfg -devicequery wake_armed Empty result set. Scheduled tasks - the main ones are not scheduled to run every hour. When go through a long list of all possible tasks, there are some that are set to be triggered every hour (e.g., MS "RacTask" whatever it is). But when I go to power options, Advanced settings, Sleep, Allow wake timers it is set to "Disable". Also, the specific task is not set to wake the computer if necessary. Power options for my Ethernet card don't enable it to wake the computer - the cable is disconnected anyway. There are no other HW devices attached - no USB disks, no keyboards / mice etc. I am really clueless and quite unhappy that it's so hard to troubleshoot this situation.

• Alienware Aurora R2 Slow Boot Up

  - by James R

  I have an Aurora R2 bought a few years ago, and recently I decided a RAM update and new Samsung SSD would be good for speed. So now it's super fast, with the exception of booting up. It still takes good 2 minutes to get past the first splash screen on the BIOS, it's only the BIOS, after that it's like lightning. I've Googled the issue, and the usual problem is the BIOS trying to boot from anything it can, with the fix being to change the boot menu. However I've changed it now, and it's still slow. When I disconnect the USB devices it speeds up, but I can't do that every time I want to boot the PC up! The only other option I can think of is upgrading the BIOS, however it seems that A04 is the recommended on for Aurora R2s, so I don't know if upgrading the BIOS could cause issues, especially not if it doesn't solve the issue. Also, when I disable my original hard drive in the boot menu, the PC won't boot up. Despite the Samsung one being fine to boot from, and the original not being needed as far as I know for starting Windows, it gives me an error message and makes me restart the PC, with a new boot configuration (with the original drive as second choice). Any ideas on how to make the BIOS boot faster? And why I need to have my original drive in the boot menu?
