Trying to install AMD's AMDGPU-PRO drivers on 21.10 wreaks havoc

[satmandu]

I'm seeing this in the xorg log:

[ 429.296] (II) Loading /usr/lib/xorg/modules/drivers/amdgpu_drv.so
[ 429.296] (II) Module amdgpu: vendor="X.Org Foundation"

And then

[ 429.385] (WW) AMDGPU(0): amdgpu_glamor_pre_init returned FALSE, using ShadowFB

Acceleration isn't being loaded, and kodi reports llvmpipe is being used.

Does xserver-xorg-video-amdgpu need recompilation for xorg 1.20.13?

This was an issue with corruption via an attempted AMDGPU-PRO driver install.

Cleaning that out fixed the issue.
