I have done some digging and trial and error with AMD’s amdgpu DC documentation and I found booting with amdgpu.abmlevel=0 amdgpu.dcdebugmask=0x410 kernel parameters to be an effective workaround. The problem is that this disables any and all panel power-saving features, and I can tell… my laptop can hardly reach 3 hours of work on a charge in this state.
Have you reported that as a bug? I think this is the right place:
For what it’s worth, I have not observed that particular problem.
I actually found the bug there - I will get around the posting the workaround that I found there shortly, because I am not sure I have seen it.
That’s strange. Me and other people seem to have experienced it even at high severity levels, while some seem to be completely unaffected. I guess it needs some weird edge case ro activate itself, or something like that
