I think I have the same issue. Ubuntu 20.04.

Title:
GPU lockup ring 0 stalled for more than X msec
Status in xserver-xorg-video-ati package in Ubuntu:
Confirmed
Bug description:
Since the update:
xserver-xorg-video-ati-hwe-18.04 (1:19.0.1-1ubuntu1~18.04.1) bionic;
which resulted from:

I've experienced GPU freezes where all video becomes unresponsive,
both Xorg and Ctrl+Alt terminal switching, and the GPU fan goes to
full. I am still able to access the system via SSH.
Sometimes dmesg ends up full of this message repeating over and over:
radeon 0000:01:00.0: ring 0 stalled for more than 24040msec
radeon 0000:01:00.0: GPU lockup (current fence id 0x0000000000009e44 last
fence id 0x0000000000009e49 on ring 0)
I sometimes get a few GPU soft reset which seem to fail in drm(?):
radeon 0000:01:00.0: Saved 110839 dwords of commands on ring 0.
radeon 0000:01:00.0: GPU softreset: 0x00000008

I've tried both 5.3.0-28-generic and 5.5.0-050500-generic from kernel-
ppa but that made no difference. It appears to be a bug in radeon.
Nothing specific makes this happen, just regular usage with a
compositing window manager. I'm not playing games or particularly
exercising the GPU. The last two times I was just reading in web
browser. It's also happened in the middle of the night while I was
asleep. Sometimes I have a few days uptime, sometimes it happens in
less than 24 hours from boot.
This never happened before the radeon update mentioned on the first
line.
I'll attach two files of dmesg output. As per
https://wiki.ubuntu.com/X/Troubleshooting/Freeze I've installed and
started apport for next time it happens.
