Created attachment 141769 [details] Static
When attempting to resume my system after a fresh boot before logging in, I get screen static instead of the login page. A console basically displays over the static about 100 “Radeon 0000:01:00.0 ring 0 stalled for more than 31414 seconds” the lengths vary. The messages end with “drm:r600_ib_test [radeon] error fence wait timed out” Then “drm:radeon_ib_ring_tests error radeon: failed testing IB on GFX ring (-110)” When logged in, I also sometimes expierience this, but pressing space, then typing my password removes the static and opens the desktop back up.

This issue sometimes also locks up my computer on resume. At that point I have to force reboot
Same here. 4.1
