            Bug ID: 111633
           Summary: amdgpu driver crash with kernel NULL pointer
                    dereference
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: not set
          Priority: not set
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org

I am running on arch linux: Linux arch 5.2.13-arch1-1-ARCH #1 SMP PREEMPT Fri
Sep 6 17:52:33 UTC 2019 x86_64 GNU/Linux

I am running wayland via sway.

My gpu is a Radeon RX Vega 64.

While in my sway session the image on my screen froze but audio from a video
continued to play. I was able to ssh in from a different machine and found this
message with dmesg:

---[ end trace 08eaa2e1d713ba4d ]---

At this point I tried killing the sway process but did not succeed even with
`kill -9`. Not even `sudo reboot` completed despite killing the ssh session. I
had to hard reset the machine.

Potentially related is that since roughly a week I have been experiencing
intermittent screen freezes from time to time that would resolve themselves
after about 10 seconds with a message like this in dmesg:

drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]] *ERROR*
[CRTC:47:crtc-0] flip_done timed out
[drm:amdgpu_dm_atomic_check [amdgpu]] *ERROR* [CRTC:47:crtc-0] hw_done or
flip_done timed out
