Most likely, this has been introduced by this commit:
commit 19b2dbde5732170a03bd82cc8bd442cf88d856f7
Author: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx>
Date: Wed Jun 12 10:15:12 2013 +0100
drm/i915: Restore fences after resume and GPU resets
At least I'm not able to reproduce it with that commit reverted. With that
commit in I was able to reproduce it quite readily on machines with Ivy Bridge
and Sandy Bridge processors.
Thanks,
Rafael
