        <pre>Sometimes KDE hangs (display/reaction is stuck), mouse moves, ctrl-alt-f1
works.
DISPLAY=:0 nohup kwin --replace & fixes the problem.

Until yesterday, I never saw any logging about it. But now there is in 'dmesg':
[110619.417764] [drm] GPU HANG: ecode 6:-1:0x00000000, reason: Kicking stuck
semaphore on rcs0, action: continue
[110619.417766] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[110619.417766] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[110619.417767] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[110619.417767] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[110619.417768] [drm] GPU crash dump saved to /sys/class/drm/card0/error

>From what I ca say, all details about my system are included in the GPU dump
attached.

I have this (in average) once every 25 working hours.</pre>
