Hi! I am a unsure how this message is appropriate here as most messages are patches.
I have temporary access (while helping the computer with a full disk situation), to test a computer with RS780C GPU, where when resuming with default ShadowPrimary off, ring 0 stalled happens on almost each resume from suspend to ram. Seems fixed by enabling ShadowPrimary (radeon driver). https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1944991 I mentions this bug on: https://bugzilla.kernel.org/show_bug.cgi?id=85421 The question is there some test I could do that would help pinpoint the problem? Like a particular drm.debug value boot parameter or something similar?
