--- Comment #26 from Niclas Zeising <zeising@FreeBSD.org> ---
I do not believe you had working graphics using amdgpu.ko even before all t=
his

The dmesg you have posted, from the broken system, indicates that amdgpu.ko
does not attach properly to the device.  There might be an issue with swras=
t in
recent versions of mesa-dri, that used to work before, that was masking thi=
s.

Comment 8 only proves that the module (and firmware modules) load, not that
they attach or work.  Can you, as also requested by Jan, provide an Xorg.log
and a dmesg from a system when this was working.

Xorg will probe a multitude of drivers (xf86-video-*) to figure out what's
going on, and which is best.  Both xf86-video-ati and xf86-video-amdgpu
requires working kernel drivers though.

Without having proper logs, from a working system, to compare with the ones
from when it is not working, it is very hard to tell what's going on.
