The patch had to get reverted as it caused regressions for Intel video
cards (see bug #423296). The problem is that without the KMS code, the
patch just causes the acpi video driver never to get initialized and by
that prevents backlight control. The fix of this bug was unfortunately

I've disabled the hack in /etc/init.d/hotkey-setup by commenting out

@Bjorn Helgass -- thanks for the pointer. That does indeed sounds

Bah didn't spot that we had a more specific fix for this specific issue.
Seems there are two issues out there. If the first patch does not fix
you then the second test is useful.
For this specific bug it seems that the original fix is good. I will

IMPORTANT:
@Andy, if the more specific fix you refer to is a hotkey-setup change,
that is only a workaround and not a sufficient fix. The kernel should
never panic or hang, no matter what user-mode applications do. If you

As a null-test I've commented out lines 30-34, which contain a
workaround for this bug, in /etc/init.d/hotkey-setup and rebooted to

Could those of you affected by this bug try reproducing this from VT-1.
Before reproducing could you run the following command which should
reduce the font size sidnificantly so that the entire panic is visible:

I've just tried to reproduce this issue on Linux workmate
2.6.27-7-generic #1 SMP. There is still a kernel panic when I close the
lid (see attached screenshot).
Because I noticed the error could be SMP-related, I disabled one of the
CPU's (sudo sh -c 'echo 0 /sys/devices/system/cpu/cpu1/online')
I have tested with the current 64bit Intrepid, using the kernel
2.6.27-4, and there is no problem. I'll try with the 32bit Intrepid when
