            Bug ID: 111299
           Summary: AMD RX 570 Black Screen/Hang at startup (AMDGpu DC
                    problem)
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: suren.karimp@gmail.com

Hello, AMD RX 570 faces a blank, black screen at boot. This started happening
after linux kernel 4.17 started enabling amdgpu DC by default, and only
solution (for now) is disabling amdgpu DC using amdgpu.dc=0 kernel boot
parameter.

Here is like to original bug, in Ubuntu's tracker:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-amdgpu/+bug/1837945

Please attach the Xorg log and output of dmesg without amdgpu.dc=0.

Its not possible to report without amdgpu.dc=0
Its absolutely impossible to boot the system, it tries to boot and then 'dies',
quite literally, as nothing functions on the system.
