On Firefox 11.0, if I enable MapsGL with Google Maps and then try to zoom in/out, my display freezes for a few seconds, the screen blanks, and then resumes functioning. dmesg output shows this:

[ 5216.319360] ALSA sound/pci/hda/hda_codec.c:1477 hda_codec_cleanup_stream: NID=0x2
[ 5716.827756] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
[ 5716.827767] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state
[ 5716.832142] [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 3198688 at 3198676, next 3198689)

I'm attaching i915_error_state in case it is useful.

My hardware is a late 2011 MacBookPro (8.2).
