Subject: g33: GPU hangs

Hi,

both yesterday and today, my GPU hung. Both happened when I opened
google front page in firefox.

I'm running 3.2.0-rc3-next-20111130. Given it happened twice in the past
24 hours, it looks like a regression from next-20111124. Or is this a
userspace issue (I might updated some packages)?

i915_error_state dumps from the two hangs are here:
