Description Kobboi 2022-02-05 00:40:29 UTC
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.

USE="X abi_x86_32 abi_x86_64 amd64 cpu_flags_x86_sse2 elibc_glibc gles2 kernel_linux llvm userland_GNU vaapi vdpau video_cards_intel video_cards_nouveau video_cards_radeon video_cards_radeonsi vulkan wayland zstd"

Downgrading to mesa-21.3.5 works fine.

Reproducible: Always

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.
Comment 4 Kobboi 2022-02-22 14:25:35 UTC
This is fixed in latest mesa-9999
Comment 5 Matt Turner gentoo-dev 2022-02-22 22:41:05 UTC
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.
Comment 6 Kobboi 2022-06-10 17:14:56 UTC
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.
