            Bug ID: 111922
           Summary: amdgpu fails to resume on 5.2 kernel [regression]
           Product: DRI
           Version: DRI git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: not set
          Priority: not set
         Component: DRM/AMDgpu
          Assignee: dri-devel at lists.freedesktop.org
          Reporter: pierre-bugzilla at ossman.eu

The upgrade to the 5.2 series of the kernel has unfortunately made my system
unusable. After resuming the system from suspend the display goes green and is
unresponsive locally. It is still up though so I was able to reach it via the
network and get some logs out of it.

Tested bad kernels:

5.2.15-200.fc30
5.2.9-200.fc30

Known good kernels:

5.0.17-300.fc30
5.1.18-300.fc30
5.1.20-300.fc30

Found some other bug reports both here and with Red Hat with similar warnings
in dmesg, but they seem to be failing right away and not after a suspend. So
I'm not sure if it's the same issue.

But report at Red Hat:

https://bugzilla.redhat.com/show_bug.cgi?id=1754252

(includes dmesg)
