Comment 1 Stanislaw Gruszka 2012-01-14 17:04:33 UTC 
This looks like memory corruption. There is known problem on hibernation with i915 driver, which can be the issue here (i915.modeset=0 kernel boot parameter workaround it).
Comment 2 Dave Jones 2012-03-22 17:04:05 UTC 
[mass update]
kernel-3.3.0-4.fc16 has been pushed to the Fedora 16 stable repository.
Please retest with this update.

Comment 5 Josh Boyer 2012-03-28 17:59:41 UTC 
[Mass hibernate bug update]

Dave Airlied has found an issue causing some corruption in the i915 fbdev after a resume from hibernate.  I have included his patch in this scratch build:

http://koji.fedoraproject.org/koji/taskinfo?taskID=3940545

This will probably not solve all of the issues being tracked at the moment, but it is worth testing when the build completes.  If this seems to clear up the issues you see with hibernate, please report your results in the bug.
