            Bug ID: 106447
           Summary: System freeze after resuming from suspend (amdgpu)
           Product: DRI
           Version: XOrg git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: kugel@rockbox.org

Similar to #104649 but happening on amdgpu.

The system immediately locks up when resuming from suspend. I get to see the
mouse cursor and the blue background of KDE's screen lock (but no password
entry or anything like that), but cannot do anything.

I can also reproduce on 4.16.7 and 4.17-rc4. This does not happen with amdg=
pu
blacklisted, or with Arch Linux' LTS kernel (4.14.39) though I get other ra=
ndom
failures on the LTS kernel.

Unfortunately, the systemd journal does not contain anything after entering
suspend so I have no possibility to get at a backtrace.
