I'm talking about the GPU hangs. If I understand you correctly, you say that with those kernel flags you can't provoke hangs anymore. My observation is that 4.13 and newer is still susceptible if you test long enough with a mix of CPU and GPU use. The original, immediate hang reported by Arch Linux users is fixed by not enabling DMAR by default, but I cannot make 4.9.59 GPU hang no matter how hard I try. With 4.13 (no DMAR) and newer it's easy, but takes a little time.</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> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
