Please attach your dmesg output and xorg log. Is this a regression? If so,
can you bisect?

It seems to have been fixed in the latest amd drm staging next. Not sure if
this means it has already been addressed and can be closed.

xorg log

the whole drm driver completely crashed and the system refused to even poweroff
a few seconds before the last line (i tried to switch to a VT to escape the
hang which did not work)

Possibly a duplicate of bug 108704. Does the patch there help?

Nevermind, you have a vega10.

Extra info, two other screens are fine. One is connected via a displayport to
dvi cable and the other is connected via hdmi. Switching the displayport ports
does not change anything.
