kern :warn : [ 2.381846] Hardware name: LENOVO 20NF0000GE/20NF0000GE, BIOS R11ET32W (1.12 ) 12/23/2019
I'm writing this on the exact same machine, but I've never seen such issues.
I recommend updating the BIOS to the current version, that resolved https://gitlab.freedesktop.org/drm/amd/-/issues/1146 for me (BIOS version 1.16 currently).
If the problem persists with that, a hardware issue does seem plausible.
