Thanks. Mika, I had already more or less backported the patch to 3.9.3 (see the other bug report: <a class="bz_bug_link bz_status_NEW " title="NEW --- - [snb] [h.264] [vaapi-mplayer] GPU hangs with both UXA and SNA after concurrent playback + GTT mapping fails after GPU hang" href="show_bug.cgi?id=63946">https://bugs.freedesktop.org/show_bug.cgi?id=63946</a>). Now I'm having difficulties getting it to crash without locking hard. Often it doesn't crash but lowers its output frequency as I explain in that bug report (which is for the same bug). I'm trying out on a lot of units todays so hopefully I strike gold! I'll keep you guys posted. Thanks for the correct backport.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
