We seem to have neglected the bug a bit, apologies.

ettavolt at gmail.com, since There were improvements pushed in kernel that will
benefit to your system, so please re-test with latest kernel and mark as
REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log)
and RESOLVED/* if you cannot reproduce.
