• Intel-microcode Package on Ubuntu

  - by Flame

  I saw the intel-microcode in the ubuntu repositories and was wondering if it was worth installing on my Yorkfield-6M based system. If so, what are the benefits from this package?

• What is the CPU microcode?

  - by golem

  Today after unpacking the initramfs file from my Linux /boot directory I found that it contains the GenuineIntel.bin file, and that that file is an image of what is called the CPU microcode. Then I found articles on ArchWiki and Wikipedia describing the subject. Now I'm not sure that my vague understanding of the subject is correct. Can anyone please explain what the CPU microcode is in plain English?

• Installed UBUNTU12.04 in Legacy, when changed to UEFI just runs the Terminal, not GUI

  - by jraulvc

  Well, I installed Ubuntu 12.04 in a Gateway NE 522 with Windows 8. First, I had to install it in Legacy mode, because in UEFI it would not run the bootable USB. In the Legacy mode it runs perfect. Once done that with help of the "Boot-Repair" I changed it to the UEFI and disabled the secure boot mode. GRUB runs fine but when I run ubuntu I get the following message: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin kvm: disabled by bios kvm: disabled by bios kvm: disabled by bios and then I just get access to the terminal. From there, I have already tried with reinstalling unity and gmd. When I try to install amd64-microcode the same error ocurrs ( microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin ) by the "updating the microcode on all online processors..." phase of the installation. Can somebody tell me how can I recover the graphical interphase of ubuntu from the terminal? Thanks a lot

• Installation problem Ubuntu 12.04 Crashing hardware error

  - by user93640

  I am running on Ubuntu 8.04 for quite some time without many problems. About almost a year ago or so I have been trying to upgrade to 10.04 LTS, but without any success. Each time when trying to upgrade or even newly install the installation process crashed after about an hour or so (I forgot exactly how long). Now I wanted to try Ubuntu 12.04 (not even installing, but I only selected "Try Ubuntu without installing") and I got similar errors. I did not try to install it, because of earlier experience with 10.04 when after I also lost 8.04 and had to install from scratch again (after which it worked). I get the following screen (as I am not allowed to upload photos here the text): 26.767262] [Hardware Error]: CPU 0: Machine Check Exception: 0 Bank 5: b200001804000e0f 26.767279] [Hardware Error]: TSC 0 26.767287] [Hardware Error]: PROCESSOR 0:6f6 TIME 1349017924 SOCKET 0 APIC 0 microcode 44 26.767297] [Hardware Error]: Run the above through 'mcelog --ascii' 26.767307] [Hardware Error]: CPU 1: Machine Check Exception: 0 Bank 1: b200000000000175 26.767316] [Hardware Error]: TSC 0 26.767323] [Hardware Error]: PROCESSOR 0:6f6 TIME 1349017924 SOCKET 0 APIC 1 microcode 44 26.767331] [Hardware Error]: Run the above through 'mcelog --ascii' 26.767339] [Hardware Error]: CPU 1: Machine Check Exception: 0 Bank 5: b200003000000e0f 26.767348] [Hardware Error]: TSC 0 26.767354] [Hardware Error]: PROCESSOR 0:6f6 TIME 1349017924 SOCKET 0 APIC 1 microcode 44 26.767363] [Hardware Error]: Run the above through 'mcelog --ascii' 26.767371] [Hardware Error]: CPU 1: Machine Check Exception: 4 Bank 1: b200000000000175 26.767379] [Hardware Error]: TSC 1bf231e65f 26.767386] [Hardware Error]: PROCESSOR 0:6f6 TIME 1349017951 SOCKET 0 APIC 1 microcode 44 26.767395] [Hardware Error]: Run the above through 'mcelog --ascii' 26.767403] [Hardware Error]: CPU 1: Machine Check Exception: 4 Bank 5: b200003008000e0f 26.767413] [Hardware Error]: TSC 1bf231e65f 26.767421] [Hardware Error]: PROCESSOR 0:6f6 TIME 1349017951 SOCKET 0 APIC 1 microcode 44 26.767429] [Hardware Error]: Run the above through 'mcelog --ascii' 26.767437] [Hardware Error]: CPU 0: Machine Check Exception: 5 Bank 5: b200001806000e0f 26.767447] [Hardware Error]: RIP |INEXACT| 60:<00000000c1018b5c> {mwait_idle+0x7c/0x1d0} 26.767464] [Hardware Error]: TSC 1bf231e674 26.767471] [Hardware Error]: PROCESSOR 0:6f6 TIME 1349017951 SOCKET 0 APIC 0 microcode 44 26.767480] [Hardware Error]: Run the above through 'mcelog --ascii' 26.767487] [Hardware Error]: Machine check: Processor context corrupt 26.767495] Kernel panic - not syncing: Fatal Machine check 26.767505] Pid: 579, comm: debconf-communi Tainted: G M 3.2.0.29-generic-pae #46-Ubuntu 26.767515] Call Trace: 26.767525] [<c158f812>] ? printk+0x2d/0x2f 26.767534] [<c158f6e0>] panic+0x5c/0x161 26.767542] [<c10247ef>] mce_panic.part.14+0x13f/0x170 26.767551] [<c1024872>] mce_panic+0x52/0x90 26.767558] [<c1024a18>] mce_reign+0x168/0x170 26.767565] [<c1024bb5>] mce_end+0x105/0x110 26.767572] [<c10252db>] do_machine_check+0x32b/0x4f0 26.767581] [<c1024fb0>] ? mce_log+0x120/0x120 26.767590] [<c15a5e47>] error_code+0x67/0x6c 26.767602] panic occurred, switching back to text console 26.768498] Rebooting in 30 seconds.. For information, I have also tried earlier Arch Linux. I can install it, but when I try to install a window manager (LXDE) again I got similar errors. Fedora also crashes when installing and also Mandriva did not work for me. Therefore I think something deep in the machine might be wrong. But as stated above I can (clean) install 8.04 and also 9.10 can be installed without problems. Also updates for 8.04 can be installed. My machine is dual boot with XP next to it on a different partition. My HW: Memory : 2.0 GiB; Processor 0: Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz; Processor 1: Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz; How can I install Ubuntu 12.04? Last option would be to completely format my machine and install everything from scratch, but even I am not sure if that would solve it in the end. Can anybody help me out?

• On boot firmware request for intel GMA 3100 chipset timing out

  - by Yannick M.

  I am currently in the process of installing a Gentoo linux box with a Vanilla 2.6.29-r5 kernel with gentoo-xen-kernel patches in order to run the Xen Hypervisor. After rebooting with the new kernel, the booting process seemed to hang on: [ 0.863005] platform microcode: firmware: requesting intel-ucode/06-0f-07 [ 60.863442] Microcode Update Driver: v2.00-xen <[email protected]>, Peter Oruba Apparently the firmware request times out after 60 seconds (/sys/class/firmware/timeout) and booting just continues. I have done some research and have found that on RHEL-4 this problem was related to the mount of /sys changed and the firmware.agent hotplug script couldn't parse the line correctly. However I am having some difficulty tracking down how to fix this on Gentoo. Any and all ideas are greatly appreciated! Thanks

• Cannot get Virtualbox to install properly on Ubuntu 12.04

  - by lopac1029

  I cannot get Virtualbox to install properly on my 12.04. I first went with a manual install for the .deb from the old builds section of the Virtualbox page. That .deb opened up the Software Center and installed. Then I got the error coming up of VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. which I can only assume was due to my Ubuntu version being 32-bit (System Details - Overview - OC type: 32-bit, right?) So I followed these instructions to remove the .deb manually, restarted my laptop, and then FOUND the actual Virtualbox install in the Software Center and installed from that (assuming it would give me the correct version I need for my system) So after all that (and then some), I'm still getting the same error when I connect to my new job's project in Virtualbox. Can anyone point me in the right direction of what to do here? This is the first time I've ever worked with Virtualbox, and no one at this company is using Ubuntu, so I'm on my own here.

• Why does cpuinfo report that my frequency is slower?

  My machine is running off of a AMD Sempron(tm) X2 190 Processor. According the marketing copy, it should be running at around 2.5 Ghz. Why is the cpu speed being reported as something lower?

  Here is an extract of results.log: MTRR validation. Test 1 of 3: Validate the kernel MTRR IOMEM setup. FAILED [MEDIUM] MTRRIncorrectAttr: Test 1, Memory range 0xc0000000 to 0xdfffffff (PCI Bus 0000:00) has incorrect attribute Write-Combining. FAILED [MEDIUM] MTRRIncorrectAttr: Test 1, Memory range 0xfee01000 to 0xffffffff (PCI Bus 0000:00) has incorrect attribute Write-Protect. ==================================================================================================== Test 1 of 1: Kernel log error check. Kernel message: [ 0.208079] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored ADVICE: This is not exactly a failure mode but a warning from the kernel. The _OSI() method has implemented a match to the 'Linux' query in the DSDT and this is redundant because the ACPI driver matches onto the Windows _OSI strings by default. FAILED [HIGH] KlogACPIErrorMethodExecutionParse: Test 1, HIGH Kernel message: [ 3.512783] ACPI Error : Method parse/execution failed [\_SB_.PCI0.GFX0._DOD] (Node f7425858), AE_AML_PACKAGE_LIMIT (20110623/psparse-536) ADVICE: This is a bug picked up by the kernel, but as yet, the firmware test suite has no diagnostic advice for this particular problem. Found 1 unique errors in kernel log. ==================================================================================================== Check if system is using latest microcode. ---------------------------------------------------------------------------------------------------- Cannot read microcode file /usr/share/misc/intel-microcode.dat.

MaxReadReq for pci://00:02:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection is low (128) [Network controller]. FAILED [LOW] LowMaxReadReq: Test 1, 2 devices have low MaxReadReq settings. Firmware may have configured these too low. ADVICE: The MaxReadRequest size is set too low and will affect performance. It will provide excellent bus sharing at the cost of bus data transfer rates. Although not a critical issue, it may be worth considering setting the MaxReadRequest size to 256 or 512 to increase throughput on the PCI Express bus. Some drivers (for example the Brocade Fibre Channel driver) allow one to override the firmware settings. Where possible, this BIOS configuration setting is worth increasing it a little more for better performance at a small reduction of bus sharing. ==================================================================================================== PCIe ASPM check. ---------------------------------------------------------------------------------------------------- Test 1 of 2: PCIe ASPM ACPI test. PCIE ASPM is not controlled by Linux kernel. ADVICE: BIOS reports that Linux kernel should not modify ASPM settings that BIOS configured. It can be intentional because hardware vendors identified some capability bugs between the motherboard and the add-on cards. Test 2 of 2: PCIe ASPM registers test.

• Ubuntu 11 and 12 initially fast but later bogs down, CPU pegged

  - by uos??

  I started with Ubuntu 11 a few weeks ago. It's on a DELL M4300 with a OCZ SSD. Default setup, except that I've installed the proprietary NVIDIA graphics and BROADCOM wireless drivers. Dual boot with Windows. If I cold boot into Ubuntu, it is very fast, just like the Windows experience that I'm used to. But SOMETHING happens, and I haven't yet determined what, but the system gets incredibly slow and stays that way. At first I thought it had to do with Adobe Flash because it seemed to be triggered by sites with Flash. But then I removed Flash and the problem remains. I thought it was just an overheating problem, but I've now upgraded to 12.04 which supposedly fixes the overheating problems I've read about. Perhaps the heat situation was brought on by Flash in my early cases? So I installed Jupiter for CPU management, but the thermometer reports a familiar Windows-side temperature of 53 degrees Celsius. Switching Jupiter to lower performance doesn't help. When I check the System Monitor application, sorting by CPU usage, there are no obvious problem processes. However, in the graphs tab, both CPU cores are pegged at 100%! I notice that the slowness seems to be similar to the extremely bad performance I got prior to installing the NVIDIA drivers. I'm not sure if that helps. This is the strangest part to me - although the temperature seems OK, even after rebooting, the system remains slow - starting with GRUB2 which is very noticeably delayed, all the way through to either Ubuntu or Windows! That's right, even the Windows side suffers effects and takes several minutes to complete booting whereas normally (with my SSD) it's ready to use in 15 seconds. The only way to fix it is to shutdown and let the parts cool down. Or maybe it just needs to completely power off and boot rather than a soft reboot, temperature has nothing to do with it? - is that possible? But know that I have never had this problem in Windows, even if Windows gets very hot (135 F) a reboot would be enough time for it to recover. For this reason, I don't think it's a heat thing, but I can't imagine what else could be surviving the reboot. I'm entirely updated - there are no pending updates. I have the Post-Release updates of NVIDIA too, btw. If this sounds CLOSE to something you know about, but one of the details doesn't line up exactly, it might be a mistake in my perception. Are there tests you can suggest to rule something out?

I don't know the relationship of which scenarios GRUB2 is also slow, but WHEN it is slow, it is slow both before the menu appears and after the selection is made - although for the diagnosis of GRUB2 it is harder for me to tell what the normal speeds should be. With SSD, I would expect that GRUB2 could load instantly, and that the GRUB2 purple would disappear instantly after the selection. The only delay to be expected is the change in graphics modes (though I couldn't guess why that ever requires any noticeable time)

• Why does 12.04 freeze when using multiple desktops?

  - by Dustin

  I am using 12.04 32-bit, upgraded from 11.10. Within the last week and a half Unity has hung on me with no option but a hard reboot, which I hate. It usually happens when I am using multiple desktops and applications and switching desktops. The screen just hangs, sometimes broken between desktops and applications, I can move my mouse but cannot click on anything. alt+f2 , HUD , super+w/s/d and alt+tab/~ does nothing, they do not activate. I let it rest for 15-20 minutes in hopes it will sort itself out but nothing. I'd hate to move to Unity 2D, but I can't risk having to do hard reboots/shutdowns, or moving to a different DE. Other information: the only PPA's I have added recently would be the word lens. 2.8GB RAM processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 127 model name : AMD Sempron(tm) Processor LE-1250 stepping : 2 microcode : 0x83 cpu MHz : 1000.000

• Unity Not loading after installing Nvidia proprietary drivers

  - by user108705

  I just got a new Nvidia GTX 650. The huge downside at this point is that whenever I use the open source driver, the computer is ridiculously slow. Whenever I use the proprietary drivers and restart, the desktop wallpaper will load and nothing more. I've tried restarting unity only to get a continuous rolling error. With the CCSM options, unity is enabled, yet nothing appears. Whenever I'm using proprietary drivers I get a microcode error which happens so quickly that I can't record the number.

• Installing Lubuntu 14.04.1 forcepae fails

  - by Rantanplan

  I tried to install Lubuntu 14.04.1 from a CD. First, I chose Try Lubuntu without installing which gave: ERROR: PAE is disabled on this Pentium M (PAE can potentially be enabled with kernel parameter "forcepae" ... Following the description on https://help.ubuntu.com/community/PAE, I used forcepae and tried Try Lubuntu without installing again. That worked fine. dmesg | grep -i pae showed: [ 0.000000] Kernel command line: file=/cdrom/preseed/lubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash -- forcepae [ 0.008118] PAE forced! On the live-CD session, I tried installing Lubuntu double clicking on the install button on the desktop. Here, the CD starts running but then stops running and nothing happens. Next, I rebooted and tried installing Lubuntu directly from the boot menu screen using forcepae again. After a while, I receive the following error message: The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again. Hitting Enter brings me to the desktop. For what errors should I search? And how? Finally, I rebooted once more and tried Check disc for defects with forcepae option; no errors have been found. Now, I am wondering how to find the error or whether it would be better to follow advice c in https://help.ubuntu.com/community/PAE: "Move the hard disk to a computer on which the processor has PAE capability and PAE flag (that is, almost everything else than a Banias). Install the system as usual but don't add restricted drivers. After the install move the disk back." Thanks for some hints!

• Uncorrectable machine check

  - by GregC

  I am experiencing rare but real unrecoverable machine checks on HP DL370 G6 dual-core Xeon server. I ran memtest86+ before, and ran CPU-intensive operations without any problems. In your opinion, does this indicate a real problem, or is it normal and expected behavior? How would you approach this problem? EDIT after some troubleshooting, it seems that these machine checks, as well as problems when showing device manager can be traced back to NC375i NICs. All is well when the NICs are not in the server. Further improvements to stability of HP Gen6 with Intel Xeon have been brought in with BIOS update in September 2013 HP Update DVD. Intel's newer microcode makes these CPUs much more stable. We haven't seen hardware-related BSODs since the update in September.

• When machine code is generated from a program how does it translates to hardware level operations ??

  - by user553492

  Like if say the instruction is something like 100010101 1010101 01010101 011101010101. Now how is this translating to an actual job of deleting something from memory? Memory consists of actual physical transistors the HOLD data. What causes them to lose that data is some external signal? I want to know how that signal is generated. Like how some binary numbers change the state of a physical transistor. Is there a level beyond machine code that isn't explicitly visible to a programmer? I have heard of microcode that handle code at hardware level, even below assembly language. But still I pretty much don't understand. Thanks!

• No video signal and server shuts down

  - by Ilya

  I have a brand new server. The motherboard is Intel S2600CP4, two 8-core Intel E5-2600 processors. RAM is 8 DIMM slots of 8 GB each (KVR1600D3D4R11SK4/32GI, I installed them into the blue slots), Power supply is 1050W Corsair. Most of the time the server won't start up - the fans are spinning, but I don't have video signal. And it keeps restarting on its own every 3 mins. But maybe after 30 mins it will eventually load and show something on the screen. I even was able to install ESXi 5.0 (vSphere) on it. It recognizes both CPUs and all of the 64GB of RAM. But even then it worked only for around 5 hours and then restarted on its own. What's the problem? That's a very expensive peace of hardware and I can't afford purchasing a new motherboard/CPU. By the way, on the front panel the "System Status" LED is constantly amber (not blinking), even when the server started successfully. And also in the BIOS I can see lots of "processor 01 unable to apply microcode update 8160" fatal errors. Please help me with issue, I will really appreciate this!

• Sandra reports my CPU as "Engineering Sample", how can I be sure this is correct?

  - by stevenvh

  I ran SiSoftware's Sandra on my new PC, and for my CPU it reports: Generation : G8 / T29 Name : TN0 (Trinity) FX/Opteron 32nm (ES) Revision/Stepping : 0 : 10 / 1 Stepping Mask : TN-A1 Microcode : MU6F10010F The (ES) is a well-known code in product development, meaning "Engineering Sample". Those are beta versions of the CPU, which still may contain some bugs, or even have features switches off. I contacted both the PC's manufacturer Medion as well as AMD about this. I had to downvote the Medion helpdesk here. The person I talked to boldly said Sandra was wrong (without knowing how Sandra got this information; he didn't even know the software), and used the word "impossible". His conclusion was "We’re not taking this in consideration for service”. Right. So, if you like Medion for their good prices, but like good support even better, you may consider buying your PC elsewhere. AMD was more helpful, but wanted to be sure before replacing the part (which I find reasonable). They suggested that I dismount the cooler from the CPU to check what was printed on it to be sure. I'm a bit reluctant here: I would have to wipe the thermal paste from the CPU, and won't know for sure my cooling will still be OK afterwards. Questions Has anybody actually found a confirmed ES CPU in her PC? Is anybody aware of Sandra erroneously reporting CPUs as Engineering Samples? How can you tell an ES, apart from the print on the package? Shouldn't Stepping Mask identify the CPU uniquely?

• How to verify power provided to processors is clean

  - by GregC

  Once in a blue moon, I am seeing a blue screen of death on a shiny new Dell R7610 with a single 1100 Watt Dell-provided power supply on a beefy UPS. BCode is 101 (A clock interrupt was not received...), which some say is caused by under-volting a CPU. Naturally, I would have to contact Dell support, and their natural reaction would be to replace a motherboard, a power supply, or CPU, or a mixture of the above components. In synthetic benchmarks, system memory and CPU, as well as graphics memory and CPU perform admirably, staying up for hours and days. My questions are: Is power supply good enough for the application? Does it provide clean enough power to VRMs on the motherboard? Are VRMs good enough for dual Xeon E5-2665? Does C-states logic work correctly? Is there sufficient current provided to PCIe peripherals, such as disk controllers? P.S. Recently, I've gone through the ordeal with HP. They were nice and professional about it, but root cause was not established, and the HP machine still is less than 100%, giving me a blue screen of death once in a couple of months. Here's what quick web-searching turns up: http://www.sevenforums.com/bsod-help-support/35427-win-7-clock-interrupt-bsod-101-error.html#post356791 It appears Dell has addressed the above issue by clocking PCIe bus down to 5GT/sec in A03 BIOS. My disk controllers support PCIe 3.0, meaning that I would have to re-validate stability. Early testing shows improvements. Further testing shows significant decrease in performance on each of the x16 slots with Dell R7610 with A03 BIOS. But now it's running stable. HP machine has received a microcode update in September 2013 SUM (July BIOS) that makes it stable.

• Kernel oops on Linux running in VirtualBox breaks some IO-related functionality on the server

  - by Kristoffer E

  We are having problems with CentOS release 6.3 running in VirtualBox on Windows 7 machines. The symptoms are the following: Everything works as normal for several hours, even days. Then something happens which breaks the system. What we still can do after this something happens: Access the web server Use existing SSH sessions to run top and free What does not work: Starting new SSH sessions (hangs after username and password is entered) Running ls in existing SSH sessions (hangs) SSI includes from our web servers that fetch data from remote machines probably more What we see on the server when this something happens is the following: Load average go from basically nothing to around 3 CPU usage is still low (5%) Disk activity is low (running iostat) Plenty of memory available Plenty of disk space available In /var/log/messages we get the following: Jun 14 01:10:48 devvm kernel: e1000 0000:00:03.0: eth0: Detected Tx Unit Hang Jun 14 01:10:48 devvm kernel: Tx Queue <0> Jun 14 01:10:48 devvm kernel: TDH <2e> Jun 14 01:10:48 devvm kernel: TDT <30> Jun 14 01:10:48 devvm kernel: next_to_use <30> Jun 14 01:10:48 devvm kernel: next_to_clean <2e> Jun 14 01:10:48 devvm kernel: buffer_info[next_to_clean] Jun 14 01:10:48 devvm kernel: time_stamp <1038284db> Jun 14 01:10:48 devvm kernel: next_to_watch <2f> Jun 14 01:10:48 devvm kernel: jiffies <103828b42> Jun 14 01:10:48 devvm kernel: next_to_watch.status <0> Jun 14 01:10:50 devvm kernel: e1000 0000:00:03.0: eth0: Detected Tx Unit Hang Jun 14 01:10:50 devvm kernel: Tx Queue <0> Jun 14 01:10:50 devvm kernel: TDH <2e> Jun 14 01:10:50 devvm kernel: TDT <30> Jun 14 01:10:50 devvm kernel: next_to_use <30> Jun 14 01:10:50 devvm kernel: next_to_clean <2e> Jun 14 01:10:50 devvm kernel: buffer_info[next_to_clean] Jun 14 01:10:50 devvm kernel: time_stamp <1038284db> Jun 14 01:10:50 devvm kernel: next_to_watch <2f> Jun 14 01:10:50 devvm kernel: jiffies <103829312> Jun 14 01:10:50 devvm kernel: next_to_watch.status <0> Jun 14 01:10:52 devvm kernel: ------------[ cut here ]------------ Jun 14 01:10:52 devvm kernel: WARNING: at net/sched/sch_generic.c:261 dev_watchdog+0x26d/0x280() (Not tainted) Jun 14 01:10:52 devvm kernel: Hardware name: VirtualBox Jun 14 01:10:52 devvm kernel: NETDEV WATCHDOG: eth0 (e1000): transmit queue 0 timed out Jun 14 01:10:52 devvm kernel: Modules linked in: vboxsf(U) ipv6 ppdev parport_pc parport microcode sg vboxguest(U) i2c_piix4 i2c_core e1000 snd_intel8x0 snd_ac97_codec ac97_bus snd_seq snd_seq_device snd_pcm snd_timer snd soundcore snd_page_alloc pcnet32 mii ext4 mbcache jbd2 sd_mod crc_t10dif ahci dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] Jun 14 01:10:52 devvm kernel: Pid: 0, comm: swapper Not tainted 2.6.32-279.el6.x86_64 #1 Jun 14 01:10:52 devvm kernel: Call Trace: Jun 14 01:10:52 devvm kernel: <IRQ> [<ffffffff8106b747>] ? warn_slowpath_common+0x87/0xc0 Jun 14 01:10:52 devvm kernel: [<ffffffff8106b836>] ? warn_slowpath_fmt+0x46/0x50 Jun 14 01:10:52 devvm kernel: [<ffffffff814595fd>] ? dev_watchdog+0x26d/0x280 Jun 14 01:10:52 devvm kernel: [<ffffffff81099138>] ? sched_clock_cpu+0xb8/0x110 Jun 14 01:10:52 devvm kernel: [<ffffffff81459390>] ? dev_watchdog+0x0/0x280 Jun 14 01:10:52 devvm kernel: [<ffffffff8107e897>] ? run_timer_softirq+0x197/0x340 Jun 14 01:10:52 devvm kernel: [<ffffffff810a21c0>] ? tick_sched_timer+0x0/0xc0 Jun 14 01:10:52 devvm kernel: [<ffffffff8102b40d>] ? lapic_next_event+0x1d/0x30 Jun 14 01:10:52 devvm kernel: [<ffffffff81073ec1>] ? __do_softirq+0xc1/0x1e0 Jun 14 01:10:52 devvm kernel: [<ffffffff81096c50>] ? hrtimer_interrupt+0x140/0x250 Jun 14 01:10:52 devvm kernel: [<ffffffff8100c24c>] ? call_softirq+0x1c/0x30 Jun 14 01:10:52 devvm kernel: [<ffffffff8100de85>] ? do_softirq+0x65/0xa0 Jun 14 01:10:52 devvm kernel: [<ffffffff81073ca5>] ? irq_exit+0x85/0x90 Jun 14 01:10:52 devvm kernel: [<ffffffff81505be0>] ? smp_apic_timer_interrupt+0x70/0x9b Jun 14 01:10:52 devvm kernel: [<ffffffff8100bc13>] ? apic_timer_interrupt+0x13/0x20 Jun 14 01:10:52 devvm kernel: <EOI> [<ffffffff810387cb>] ? native_safe_halt+0xb/0x10 Jun 14 01:10:52 devvm kernel: [<ffffffff810149cd>] ? default_idle+0x4d/0xb0 Jun 14 01:10:52 devvm kernel: [<ffffffff81009e06>] ? cpu_idle+0xb6/0x110 Jun 14 01:10:52 devvm kernel: [<ffffffff814e433a>] ? rest_init+0x7a/0x80 Jun 14 01:10:52 devvm kernel: [<ffffffff81c21f7b>] ? start_kernel+0x424/0x430 Jun 14 01:10:52 devvm kernel: [<ffffffff81c2133a>] ? x86_64_start_reservations+0x125/0x129 Jun 14 01:10:52 devvm kernel: [<ffffffff81c21438>] ? x86_64_start_kernel+0xfa/0x109 Jun 14 01:10:52 devvm kernel: ---[ end trace 2c7bb984812cf120 ]--- Jun 14 01:10:52 devvm kernel: e1000 0000:00:03.0: eth0: Reset adapter Jun 14 01:10:53 devvm abrtd: Directory 'oops-2013-06-14-01:10:53-1537-0' creation detected Jun 14 01:10:53 devvm abrt-dump-oops: Reported 1 kernel oopses to Abrt Jun 14 01:10:53 devvm abrtd: Can't open file '/var/spool/abrt/oops-2013-06-14-01:10:53-1537-0/uid': No such file or directory Jun 14 01:10:55 devvm kernel: Bridge firewalling registered After this we see for a while, every two minutes: Jun 14 01:14:22 devvm kernel: INFO: task events/0:19 blocked for more than 120 seconds.
