            Bug ID: 111848
           Summary: AMDGPU and display fails after resume from suspend
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: not set
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: mkj@gotu.dk

Sometimes after my machine resumes from suspend my display stays off with no
signal, and USB keyboard (Num lock) and mouse doesn't react.

This time I managed to SSH into the machine and gather some logs after it
failed resuming.

I have experienced this with different kernels and under different Linux
operating systems, like Debian and Gentoo, but it is not happening often enough
for me to sense a pattern.

I will attach log files to the best of my abilities according to:
https://amdgpu-install.readthedocs.io/en/latest/install-bugrep.html

Can confirm this problem on

kernel-5.2.17-200.fc30 
kernel-5.2.9-200.fc30
kernel-5.2.5-200.fc30
kernel-5.3.1-150.vanilla.knurd.1.fc30

Suspend & resume work flawlessly on

kernel-4.20.16-200.fc29

Is there a Fedora workflow for bisecting?
Also, do I need to take care of any GPU firmware or is it just the kernel?

Don't worry about the firmware, just the kernel is fine.  Here's a bisect howto
tailored to fedora:

The kernel-package.py script is broken.
I'll build kernels directly.
Git bisect says approximately 13 steps are required between v4.20 and v5.0.
Will report back in ~14 days when that's done (bug manifests only after some
uptime).

Bisection turns out to be harder than anticipated because there is another bug
that makes the system freeze on suspend (not reported yet).

Anyways, this seems to be a duplicate of
