dmesg log

This is quasi-bisected while I need apply patch newer than first bad commit.

So keep in mind that i always apply: drm/amd/amdgpu: Remove double lock from
gfx v6
see: https://bugs.freedesktop.org/show_bug.cgi?id=97594

kernel: drm-next-4.9-wip
boot with dpm=0 works, 
dmesg is attached

"first" bad commit: drm/amd/amdgpu: Tidy up SI SMC code
https://cgit.freedesktop.org/~agd5f/linux/commit/?h=drm-next-4.9-wip&id=c4f7beed7017652ca39fb475a1f423084944975e

Due i cannot simple revert i don't know if it's only problem.
