Suspecting corrupted VBIOS after update of AMDGPU on AMD7870

[Jacob Hrbek]

I'm sorry for the wrong link, this one should work
https://gist.github.com/Kreyren/3e55e9a754e58956e1690e38b1888de7

I've manually compiled kernel-5.5 which results in this dmesg -

If relevant i've used this config
https://gist.githubusercontent.com/Kreyren/7b20ad875ca42381d4a0a8e5b1b26a2c/raw/171747682e49fe28cb653b2e45ee42390ca59338/gistfile1.txt
(grabbed from debian)
