[22.0.0_rc{1,2}] radeonsi: broken support for HD7850 (radeon 0000:0b:00.0: ring 0 stalled for more than...)
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.
Downgrading to mesa-21.3.5 works fine.
0b:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP]
Also logged as https://bugs.gentoo.org/832730 but was asked to report upstream.
