SUMMARY Frequent freezes in Kubuntu 19.04 using a Radeon VII. The freezes did not occur with a Vega64 on the same system. Windows on the same system is stable. STEPS TO REPRODUCE 1. Random freezes. 2. 3. OBSERVED RESULT The freezes can occur at any time. But they are more frequent soon after rebooting. The screen completely locks up. Some times sound will continue and then also freeze shortly afterwards. This can happen in any application. I can still SSH into the machine from another machine so the rest of the machine is still responsive. I see the following errors in /var/log/syslog: Sep 23 17:04:43 Hades dbus-daemon[1681]: [session uid=1000 pid=1681] Activating service name='org.kubuntu.DriverManager' requested by ':1.6' (uid=1000 pid=1761 comm="kded5 [kdeinit5] " label="unconfined") Sep 23 17:04:43 Hades dbus-daemon[1681]: [session uid=1000 pid=1681] Successfully activated service 'org.kubuntu.DriverManager' Sep 23 17:05:04 Hades kernel: [ 257.532173] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=9177, emitted seq=9179 Sep 23 17:05:04 Hades kernel: [ 257.532294] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process kwin_x11 pid 1803 thread kwin_x11:cs0 pid 1891 Sep 23 17:05:04 Hades kernel: [ 257.532301] amdgpu 0000:05:00.0: GPU reset begin!
