Bug#705635: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
Same here.
After upgrade to Debian Wheezy I was unable to start gnome-shell
standard session as my notebook was hanging hard, sometimes the pointer
can still be moved and gnome-shell segfauling.
When there is not hard lock up there are entries in kern.log:
May 23 14:34:12 casper-hp kernel: [ 157.099910]
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapse

This seem to be those bugs:

https://bugs.freedesktop.org/show_bug.cgi?id=55984
As stated in the above links, the problem is solved in kernel 3.8.
I can confirm that installing linux-image-3.8-2-amd64 (3.8.13-1) from
Sid solves this problem.
