Re: Problem Report: i915 driver most probably causing freezes on FreeBSD 13.1-RELEASE

Can you trigger OpenGL crash via graphics/kmscube or glmark2-drm from
benchmarks/glmark2 when running under console?

0x0402 is Haswell, so OpenGL is driven by either i965 or crocus. In graphics/mesa-dri
crocus is currently disabled by default unless MESA_LOADER_DRIVER_OVERRIDE=crocus, see
https://gitlab.freedesktop.org/mesa/mesa/-/commit/988762679ccf

src/loader/meson.build:
  _prefer_crocus = get_option('prefer-crocus')
  if _prefer_crocus == 'auto'
    _prefer_crocus = 'false'
  endif

Maybe try crocus from graphics/mesa-devel. i965 is gone upstream (Mesa >= 22.0.0).

Try upgrading xorg-server to 21.1.4 by switching to /latest package repo.
1.20.14 on /quarterly will be unsupported after 2022Q3 branch EOL around
2022-10-01 (~1 week from now).

Looking at the end of Xorg.log I don't see anything suspicious. Is it
really the log from when Xorg crashed and not from a separate instance
run by the Display Manager?
