Waiting until what looks like X finish initializing, putting the computer to sleep and awake it again almost always works as a workaround. dmesg: [ 5.165441] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed: 5 tries [ 5.165453] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed And it looks like the DisplayPort is not initialized correctly. "Black screen" in this context means nothing works (no TTY:s). [2] Disabling si_support (GCN 1.0) in grub results in system always boot correct from a shutdown state but awake from sleep doesn't work. [3] Switching to the experimental (for GCN 1.0 cards) amdgpu driver result in the same behavior as in [2].
