4.4.0-12-generic this problem doesn't appear anymore. I'll mark this as
fixed.

Title:
Lenovo E460 kernel panic with onelink pro dock and external screen
Status in xorg package in Ubuntu:
Fix Released
Bug description:
I have a Lenovo ThinkPad E460 and a Lenovo ThinkPad OneLink Pro Dock.
Everything works fine, except for the external screen ports on the
dock. When I plug in an external screen to the DVI or DisplayPort, the
system freezes. I've attached a screenshot of the errors I get.
The setup was working fine in Windows 10. The HDMI port on the laptop
works fine.
