Public bug reported:
I have a Lenovo X1 Yoga 2nd gen along with the Lenovo thunderbolt
docking station. Initial connection to the dock works great, but after
a few plug/unplug and suspend/resume cycles, the system gets in a state
where a reboot is needed to make the dock work. The displayport
connection still works so my external monitor gets the right display,
but the thunderbolt / PCIe connection does not and so the USB and
network ports in the dock aren't usable. I assume it is connected to
the kernel messages like
