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

The issue is occurring with a pretty old kernel and in bsd ring.
Reassigning to libva component.
There were improvements pushed in kernel and libva that will benefit to your
system, so please re-test with latest kernel & libva and mark as REOPENED if
you can reproduce (and attach fresh gpu error dump & kernel log) and RESOLVED/*
if you cannot reproduce.
