Bug#626022: linux-2.6: Attempting to reboot on [U]EFI systems causes kernel hang
Package: linux-2.6
Version: attempting to reboot on UEFI systems causes kernel hang
Severity: important
Tags: upstream
When attempting to reboot my my UEFI enabled system, the system hangs when
calling reboot requiring me to manually reset the system via the reset switch.

As you can see this is on a P8P67 Motherboard.
It seems as if this has recently been reported at Ubuntu's Launchpad as well:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/721576
Which also suggests a workaround of adding reboot=a,w to the kernel command
line, I shall try this later on this evening.
