Multiple days and still same good result with the state of DRM in 4.9.56. The quickest was with 4.13, not even needing an hour before the workload described above triggers the bugs. 4.14-drm-tip takes anywhere from 2 to 8 hours before the GPU hangs. So I agree with Ivan, 4.9 has the most stable DRM right now and is sadly not the extended LTS release, so either 4.4 needs a backport of 4.9 DRM or 4.14 fixes for the regressions. Not sure what is more likely to happen.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
