            Bug ID: 209721
           Summary: No output after AMDGPU loads.
           Product: Drivers
           Version: 2.5
    Kernel Version: Linux Master branch
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: blocking
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri at kernel-bugs.osdl.org
          Reporter: haxk612 at gmail.com
        Regression: No

I sadly cant even get an dmesg from journalctl or anything.
when i enable loglevel8 it shows me that fb0 is giving word to AMDGPU module
and then screen goes black turns back on but no output at all.

System Specs: Acer Nitro 5 AN515-42
GPUs: AMD Vega 8 (iGPU in Ryzen 5 2500U)
      AMD Radeon RX560X (dGPU)

If there is any way you know of to be able to grab logs i will gladly do it.

It should be noted that 5.9 tag works just fine. So the bug was introduced in
one of the drm-next merges.
