Yep, probably a dupe of that bug. Actually we'd probably dupe to bug 727594 even though the IPEHR is a bit different, upstream thinks all the i915 gpu lockups are instances of that same bug. There is a patch on the upstream bug report which needs tested (sounds uncertain if it'll fix this case too.)
