I'm now getting radeon GPU lockup with the Ubuntu 5.11.0-25 and 5.11.0-27 kernels.
UPDATE Sep 10 2021: The 5.11.0-34-generic kernel works fine.
The 5.8.0-63 kernel and all previous work fine.

$ lspci | grep ATI
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV620 GL [FirePro 2450]
06:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] RV620 GL [FirePro 2450]

I use three (of four possible) 1600x1200 LCD monitors on the four FirePro outputs.

Selected lines from /var/log/syslog are attached. These are the actual repeating lockup lines:

Aug 17 15:20:44 linux kernel: [ 7403.029720] radeon 0000:06:00.0: GPU lockup (current fence id 0x0000000000000001 last fence id 0x0000000000000002 on ring 0)
Aug 17 15:20:44 linux kernel: [ 7403.541687] radeon 0000:06:00.0: ring 0 stalled for more than 11304msec

The last two lines "GPU lockup" and "ring 0 stalled" repeat over and over. The keyboard and the X11 display won't respond. I can ssh into the machine, and I can type "reboot", but it hangs somewhere in the shutdown (or else it is waiting for something longer than I'm willing to wait). The system reboots when I type ALT-SYSRQ-B on the keyboard, and I select the 5.8.0-63 kernel and everything is fine.
