GPU lockup ring 0 stalled for more than X msec

After happening every day for a week, this hasn't happened again since I logged this bug.

I also disabled Firefox WebRender so maybe that was a contributor.

I'll re-open if I can provide any useful data.

I have very old siemens computer. The affected it after I upgraded ram from 2 to 4 GB.
I found some rumours that the bug was introduced with kernel 4.10. I'm not able to debug the problem. Anyhow I attached dmesg log maybe it help to fix this annoying bug.

seems to be very similar: https://gitlab.freedesktop.org/drm/amd/issues/773

I reduced RAM back to 2GB on my siemens computer, and all works fine.
I haven't experienced crash since then.
My computer is not stable with 4GB of ram.

Recently I'm also experiencing this on:

Ubuntu 20.20 (Linux 5.8.0-41-generic)
AMD® A10-5750m apu with radeon(tm) hd graphics × 4

This is an older system indeed, but still...

I am also experiencing this issue. I was using 18.04.5 and did not have the issue. I did a new install of 20.04 with the same hardware and the problem started. It continues after upgrade to 20.10.

I hope I did this properly, but I changed status back to new. This is still an issue, and if more info is needed I can provide it, at least from my end of things.

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

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.

I think I have the same issue. Ubuntu 20.04.

Status changed to 'Confirmed' because the bug affects multiple users.

For what it's worth, I don't get these messages anymore since I replaced my CPU fan.

My graphics card has passive cooling only, and relies on air flow in the case, so CPU and case fans. The CPU fan was dead, had probably been for a long time. I replaced it and have not seen this issue ever since. Of course it probably is something else, but you could try and monitor temperature, just in case.

I had the same problem with Ubuntu 20.04 LTSP client: black screen during boot, keyboard and mouse don't work, ssh works and "ring 0 stalled" messages in the system log. I had to switch to Ubuntu 18.04 which works fine.
