This is not a duplicate of #477256. That bug is about the i855 driver and does not mention the i915 driver or the "[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung" syslog entry.

This is the exact message I see in the syslog:

Oct 8 01:56:20 localhost kernel: [175362.180132] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
Oct 8 01:56:20 localhost kernel: [175362.180146] render error detected, EIR: 0x00000000
Oct 8 01:56:20 localhost kernel: [175362.180172] [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 (awaiting 14505009 at 14505008)

After this the GPU does not work. I can restart X but only get a blank screen with a mouse on it.

Anyone find any workarounds for this? One might be to use the vesa driver but that is less than ideal.
