Forwarding this bug from Ubuntu reporter david reeves:
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/856423

[Problem]
GPU lockup that might be related to power management and/or screen brightness.

We've received a dozen reports with this same error code in recent weeks.

[Original Description]
not sure what happened
I left the laptop running and the screen goes black . when i try to get the screen back by moving the mouse it wont reappear. the only way i can get it back is to hit the power button then the enter button and shut down the machine

If the dimming of the screen is related, then this crash happens before the screen dims and does not come back. See bug 850749 (and bug 856423, which is a duplicate of this bug)

Comment 5 Paulo Zanoni 2011-11-09 08:34:01 UTC

Some Launchpad reporters claim this was fixed by Oneiric updates, but there are some duplicates appearing even after people said the bug was fixed...

Comment 6 Chris Wilson 2011-11-09 08:39:59 UTC

Nope, this bug won't just vanish like that, it is more likely to be a dupe of bug 36246.

Comment 7 Chris Wilson 2012-04-16 05:14:58 UTC

Should be improved by:

commit 14667a4bde4361b7ac420d68a2e9e9b9b2df5231
Author: Chris Wilson <chris@chris-wilson.co.uk>

    drm/i915: Finish any pending operations on the framebuffer before disabling
    
    Similar to the case where we are changing from one framebuffer to
    another, we need to be sure that there are no pending WAIT_FOR_EVENTs on
    the pipe for the current framebuffer before switching. If we disable the
    pipe, and then try to execute a WAIT_FOR_EVENT it will block
    indefinitely and cause a GPU hang.
    
    We attempted to fix this in commit 85345517fe6d4de27b0d6ca19fef9d28ac947c4a
    (drm/i915: Retire any pending operations on the old scanout when switching)
    for the case of mode switching, but this leaves the condition where we
    are switching off the pipe vulnerable.
    
    There still remains the race condition were a display may be unplugged,
    switched off by the core, a uevent sent to notify the DDX and the DDX
    may issue a WAIT_FOR_EVENT before it processes the uevent. This window
    does not exist if the pipe is only switched off in response to the
    uevent. Time to make sure that is so...

With patches also to SNA to reduce the race window and another patch pending.
