if this was after a hibernate, it's possible that this may be memory corruption from the i915 driver. (We have a ton of bugs about that already).
*** Bug 811616 has been marked as a duplicate of this bug. ***
We've not seen this again since the i915 fix went in. Closing this out. If you see it again with 3.4.11 or 3.5.4 or newer, please let us know.
