[Pkg-raspi-maintainers] Bug#1006303: vc4-drm: probe of gpu failed with error -2

[Andy Valencia]

Package: raspi-firmware
X-Debbugs-Cc: deb-bugs at vsta.org
Version: 1.20220120+ds-1
Severity: important

Dear Maintainer,

After a dist-upgrade on 2/21/2021, DRM is apparently broken
on my 8gb Pi4:

[    6.419137] vc4-drm gpu: failed to bind fe400000.hvs (ops vc4_hvs_ops [vc4]): -2
[    6.439133] vc4-drm gpu: master bind failed: -2
[    6.455849] vc4-drm: probe of gpu failed with error -2

This is a stock install of bookworm/sid.  I can start Xorg,
but video rendering is via SDL:

    [vo/sdl] Using opengl
    [vo/sdl] Warning: this legacy VO has bad performance. Consider fixing your graphics drivers, or not forcing the sdl VO.

With marginal video rendering performance.

Before this latest update, it was working quite well.  apt
history does show the firmware being updated:

    raspi-firmware:arm64 (1.20210805+ds-1, 1.20220120+ds-1)

(I can attach the full apt history if it helps.)
