Public bug reported:
When I plug in a second Monitor using a DisplayPort cable, the system
becomes barely responsive (all you can do is move the mouse very slow)
and [kworker/1:2] is using 100% CPU in top. A few seconds after pulling
the cable out the system works normally again.
Filing this against the driver and not the kernel as the nvidia driver
works somewhat fine.
