<pre>I could reproduce it now with different DELL docking station - happens only
with 2 screens with exactly this (07cf212bc704357ee60aba52ec40bab538222040)
drm-tip.
There are lots of time outs like:
[ 34.784041] [drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:55:pipe
B] flip_done timed out
[ 45.024099] [drm:drm_atomic_helper_wait_for_dependencies] *ERROR*
[CRTC:55:pipe B] flip_done timed out
Everything hangs, however ssh access works. I will now investigate what is the
problem.</pre>
