Public bug reported: My system intermittently locks up every few days. It does not seem to correspond to a particular program or action. When that happens, the screen goes to black, then returns after a few seconds. At that point, the time on the clock is static and indicates that the screen is frozen, but audio continues to play for 30 seconds to a minute. The keyboard and mouse do not affect what's being displayed, but I can Alt - SysRq - REISUB to restart.
Every time (7 crashes and counting), /var/log/kern.log indicates that kernel: [353692.378886] radeon 0000:03:00.0: ring 0 stalled for more than 10280msec kernel: [353692.378896] radeon 0000:03:00.0: GPU lockup (current fence id 0x00000000006e96e5 last fence id 0x00000000006e96e9 on ring 0) just before the system locks. Different ring numbers are reported as stalling at different times. As per the instructions, I posted a question about this issue at: https://askubuntu.com/questions/937792/system-lockup-radeon-ring- stalled-for-more-than-10280msec?noredirect=1#comment1486875_937792 but I have not received many responses.
