Machine starts gdm at boot, but I never get a login prompt, the screen is either black or (most of the times in fact) just garbage (from some random piece of memory?). Attached is the full journalctl output, from boot to forced shutdown. Things go wrong on line #2010: feb 04 01:38:28 tanagra kernel: radeon 0000:0b:00.0: ring 0 stalled for more than 10134msec but the action that triggered it of course started 10.134 seconds before that.

I git-bisected the problematic commit to be: https://gitlab.freedesktop.org/mesa/mesa/-/commit/5406ad93a9e61cc2088c7fd4b5d038db794bd4f5 . I have pinged the author on the freedesktop gitlab.
This is fixed in latest mesa-9999
Awesome, thank you for reporting the bug upstream and bisecting it. Since the commit is tagged with Fixes: it'll get cherry-picked to stable releases soon.
A similar problem has re-appeared though not as easily reproducible (22.1.1 but probably earlier?). Just mentioning in case someone else is experiencing that too.
