Subject: linux-image-amd64: can't start X anymore with linux-image-5.14.0-1

Package: linux-image-amd64
Version: 5.14.6-2
Severity: important

Dear Maintainer,

after today's kernel-upgrade in testing to linux-image-5.14.0-1-amd64 (version 5.14.6-2)
X cannot be started on my machine neither by lightdm nor by hand with startx.
Booting with linux-image-5.10.0-8-amd64 (version 5.10.46-5) all works fine.

Hardware: AMD Ryzen3 3200G with Radeon Vega Graphics managed by amdgpu

I'll attach the relevant log-files for both kernels. But looking at Xorg.0.log it seems
as if the amdgpu-driver doesn't recognize the GPU any more and lists all supported
chipsets instead.
And than:

Whatever this causes, it only happens with the new kernel and makes it useless for me.
Would be nice if you had a look into it ;-)
