--- Comment #3 from meep at binary-kitchen.de ---
We have some crashes probably related to this at
https://gitlab.freedesktop.org/drm/amd/-/issues/1591  

I have the exact the same kernel log, however missing the very first line.

I can trigger this bug reproducibly by just opening a lot of xterm windows if
truetype fonts enabled.

My Machine is brand new. So I dont have any last-working-setup/date.
Thinkpad T14s. AMD U4750 (no dedicated GFX).
Archlinux updated from 19.5.2021 till 27.5.2021 for sure has this bug in it.

Tried various kernel down/grades from 5.10.1 to 5.12.6, all crashed.
Tried a lot of different linux-firmwares too.

Complete Archlinux Rollback to 1/March/2021 stopped crashing.
I chose this date randomly so some days later everything might be fine too.

Not experienced in that whole Graphics-System and how packages/components
interconnect.

Willing to help pinpointing the problem, testing fixes/solutions.
