Public bug reported:
I have a Lenovo Thinkpad X260 docking with a Lenovo 40A20090UK docking
station. I have two monitors plugged into the back of the dock via its
two separate displayport connectors. Booting the machine whilst docked
causes the machine to freeze when it is undocked. Same for booting
undocked, then docking.
