reboot

I have installed Ubuntu 12.04 on several Dell c6220 servers. The install was successful and all hardware is recognized.

The problem that I am running into is that when issuing the reboot command or when pressing ctrl-alt-del, the server shuts down, but never comes back up. Instead, the fan revs up to full speed and stays that way until I power the server down.

Once the server has been powered down via the power button, Ubuntu will boot just fine -- until the next reboot.

I have found that by rebooting the server via the DRAC web interface will reboot the server correctly.

I have also found that this problem does not exist with CentOS -- I can press ctrl-alt-del all day long and it always comes back up.

I've tried several kernel parameters such as:

reboot=bios
reboot=pci
reboot=acpi
reboot=cold
acpi=off
noapic

Nothing seems to work.

I have also tried upgrading to kernel 3.4, but no change there, either.

Has anyone run into a similar problem or any pointers on troubleshooting?

Thanks,

Joe

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.
