Public bug reported:
Binary package hint: acpi-support
I have several partitions, 1 with Win 7, 1 with Ubuntu 10.04 and 1 with Ubuntu
11.04.
When I reboot from Ubuntu 11.04, the PC crashes/reboots itself. If I shutdown
from Ubuntu 11.04, on restart the PC crashes during POST. After the
crash/reboot, everything works fine.
Here are the different scenarios:
Reboot from Ubuntu 11.04 back into Ubuntu 11.04: No issue.
Reboot from Ubuntu 11.04 into other OS: Crash and reboot after more or less 40
seconds
Reboot from Ubuntu 11.04 and wait in grub2 menu screen: Crash and reboot after
more or less 40 seconds.
Shutdown from Ubuntu 11.04: Crash and reboot during POST. No issues afterwards
in Windows or Ubuntu
Reboot or shutdown from Windows 7: No issues
Version: Ubuntu 2.6.38-8.42-generic-pae 2.6.38.2
It seems to affect a few users (someone posted this issue in Ubuntu forums)
I chose acpi-support as the culprit package, but it was really a shot in the
dark.
** Affects: acpi-support (Ubuntu)
