I will do that next time I see this. A question: is there a signal I can send to the process (SEGV?) to trigger an Apport bug report in /var/crash? And would that make things easier for you?

I have seen this using two identical docking station plus monitor combinations. I am still trying to find a pattern. I was able to ssh in and use apport to save this bug information. The gnome-shell process was hung at 100% CPU utilisation.
