https://bugzilla.kernel.org/show_bug.cgi?id=198883 --- Comment #23 from Andrey Grodzovsky (andrey.grodzovsky@xxxxxxx) --- Looked a bit more into the ftraces, fence from gfx ring, context=80 seqno=10 which is a drm_sched_fence.finished fence is never signaled so next time when same slot (slot 10) needs to be reused it waits for ever for that fence to be signaled. finished fence is signaled once the HW fence wrappinig the IB is signaled so looks like the related IB never completed execution. You can try and generate gfx ring dump with UMR tool (https://cgit.freedesktop.org/amd/umr/) Also try applying the attached patch to your kernel to improve UMR output Once installed, please reproduce the issue and then attach output from following command sudo umr -O verbose,follow_ib -R gfx[0:2047] -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
