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.
Screenshot: http://twitgoo.com/29bq1c
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.

I also had this problem on my own system, but it is fixed now.
I bisected the fix to:
commit f70e957cda22d309c769805cbb932407a5232219
Author: Matthew Garrett <[email protected]>
Date: Wed Jul 6 16:52:37 2011 -0400
x86: Don't use the EFI reboot method by default
which is basically equivalent to the workaround!
I'll also apply this fix to squeeze as it's so simple.

One of the nice things about standards is that there are so many of them.
