I can confirm this also with quantal kernel 3.5.0-27 on my lenovo E530:
uname:

dmesg:
[19832.492304] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU

It happens randomly 3-5 times per day - the display completely freezes and only
mouse is moving. Restart is then necessary. It is impossible to seriously work
with the laptop.
