inxi output
The system doesn't wake up correctly from susped to RAM. Sometimes it works,
often the screen comes back black or with the last view before suspend, frozen.
Happens more often when docked. SSH is still possible in most cases, only the
graphical interface is dead.
dmesg shows this:
[32756.191289] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring sdma0 timeout,
last signaled seq=168244, last emitted seq=168246
[32756.191301] [drm] IP block:sdma_v3_0 is hung!
[32756.191305] [drm] GPU recovery disabled.
It doesn't matter whether suspend was called via lid switch, button, GUI or
shell script, or if the lid signal is disabled or not.
OS: Fedora 28, kernel 4.17.19-200.fc28.x86_64</pre>
