I think I have this exact same issue with my RX 580. When amdgpu.dc=1 is initialized at boot, the console goes blank as it thinks all displays are disconnected. Xorg is not able to enable the display either. With amdgpu.dc=0 all is fine. Tried with various (mostly Debian) kernels from 4.16 through 4.18~rc4, all have the issue. I'm building a 4.18~rc7 from kernel.org now to rule out Debian patches being the issue and will be able to provide logs.
Should I open a new issue as this one has been closed? Or can this one be reopened?
Feel free to create a new ticket and include your dmesg and Xorg logs.
