We seem to have neglected the bug a bit, apologies. Jonas Jelten, since There were improvements pushed in kernel & 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.

Timeout. Assuming that this is not occurring anymore. If this issue happens again, re-test with latest kernel & libva and REOPEN if you can reproduce (and attach fresh gpu error dump & kernel log)
