Thanks, seems my search-foo didn't find that one. FWIW, the mentioned fix https://github.com/jlindgren90/linux/commit/8cf17c25e2d2644fa6dfc3d7de6b3b35689d4db0.patch solves the problem for me (on top of 6.1.30). Dear future reader, please be reminded this is still an ongoing issue, or as written in the drm/amd ticket: "this patch is just papering over underlying issues". So while it makes that specific setup usable, the ultimate fix is still not available yet. Check on the other bug tracker, or re-try newer kernel releases. |
