Just got this problem again on the latest F22 kernel.

Linux titan.davidstrauss.net 4.1.8-200.fc22.x86_64 #1 SMP Tue Sep 22 12:13:21 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Also have this on linux 4.3.

HW:
- Thinkpad T440s
- i5-4200U with HD Graphics 4400
- Lenovo Ultra Dock

SW:
- Arch Linux
- Linux 4.3
- xf86-video-intel 2.99.917+478+gdf72bc5-3

Happens when i wake the system from standby in the docking station.
If you need more info, please tell.

Ultra dock has MST, maybe this is the problem.
