@Harry Wentland,
i am trying kernel 4.17.0-rc1 (patches already merged by linus):

With 'amdgpu.dc=1', i get a black screen now at login (perhaps related to this
dc issue). I found 2 new warnings and call traces in kernel log, like:

Apr 18 18:28:41 debian kernel: WARNING: CPU: 10 PID: 345 at
drivers/gpu/drm/amd/amdgpu/../display/dc/dm_services.h:132
generic_reg_update_ex+0x102/0x150 [amdgpu]

...
