--- Comment #2 from Piotr Kołaczkowski <pkolaczk at gmail.com> ---
I have the same problem. 
Occurs very often on newly released 4.14.rc1 kernel on Dell Precision 5520.
Setup: Dell Precision 5520 + external Dell U3011 display connected through the
WD15 dock and miniDP. 

Here is one such encounter followed by a total crash / kernel freeze.
This one happened after suspending, then disconnecting the laptop from the dock
and resuming:
