Xserver crashes whenever I reconnect my laptop to the docking station.

[Łukasz Maśko]

It used to work some time ago, but now it doesn't. I have a Dell latitute 
E7250 and a docking station. Whenever I connect my laptop, it crashes with the 
following message in the log:

Is it a kernel driver problem or Xserver itself? I'm using xorg-xserver-server 
1.19.1-1 and kernel 4.9.6-1.
