Hello Alex,
after your latest Navi merge 'amd-staging-drm-next' is broken with
Polaris 20.
It hangs with very light gray (mostly black) screen after first mode
switch.
Tested commit:
317d5033ab6c (HEAD -> amd-staging-drm-next, origin/amd-staging-drm-next)
drm/amdgpu: add job->preamble_status back to status value
Even run mode 3|1 with grub2 do not works.

I have to roll back before Navi commits to get working
'amd-staging-drm-next' kernel, again.
Maybe you have some 'spare' time despite all your Navi enablement work
to lift 'amd-staging-drm-next' to at least 5.2-rc6 (the Steam TCP
thing).
Greetings,
Dieter
