--- Comment #4 from tones111@hotmail.com --- I'm seeing the same problems when running 5.2.x that were not present in 5.1. The commit above is the source of the visual artifacts, but I believe the lockup issue was introduced later. Is there any help I can provide in testing a fix?
It looks like there might have been some previous effort here: https://www.spinics.net/lists/amd-gfx/msg32192.html
I created https://bugzilla.kernel.org/show_bug.cgi?id=204611 that can be used to track the lockup issue.
