I have the same effects as the description with the following graphics

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] RV630 PRO [Radeon HD 2600 PRO AGP]

- IRCC Ubuntu 16 would not spot any problems.
- Lubuntu 18.04 kernel 4.15.0-88-generic would spot the problem very seldom, at 
undetermined situations. You can live with the problem...
- Lubuntu 20.04 kernel 5.4.0-39-generic the problem is reproducible 
deterministacally with certain actions. Opening specific websites, or simply 
open a video with VLC (you cannot live with the problem)

  radeon 0000:03:00.0: ring 0 stalled for more than 10000msec

Status in Linux:
  Won't Fix
Status in linux package in Ubuntu:

Bug description:
  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 
  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.
