Start Ubuntu 18.04 with X/Unity & latest git gfx/media stack 2. Run large number of Wayland test cases which fail immediately at start because there's no Wayland. I don't think these are relevant, but if some of them briefly open window before exiting, it does exercise i915 3. Run 3x 7 (very heavy / low FPS) windowed GPU bandwidth tests 4. Run 3x 8 different FFmpeg QSV (=using MediaSDK) transcode operations, alternating betwee multiple processes (parallel process count being from 5 to 50) and single transcode process versions of them 5. Run same things as in 4), but using MediaSDK (transcode sample app) directly In some of these 1/3 freeze occurrences, freezing happens in step 3), sometimes in step 4). After Media freeze, reboot seems stuck at shutdown, device needs to be power-cycled.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
