Hi Chris, Ville, I know that you've been looking into $subject lately. AFAIK you've gotten some progress, but you are still sometimes seeing hangs in your testing, right? Several people who are following: https://bugzilla.kernel.org/show_bug.cgi?id=109051 Have been testing two patches of mine which are a rough attempt at fixing this. One makes the code change the GPU-freq less frequently and as such is probably superseded by your work on this. The other patch disables the CPU C6 C-state (while keeping C7), because many errata mention issues with C6. Various people have reported good results with that patch, even in cases where the GPU-freq related patch does not help. The patch is here: https://bugzilla.kernel.org/attachment.cgi?id=260585 Perhaps you can add this to your test workload and see if then the hangs you are seeing do completely go away?
