Description Jan Hutař 2017-07-14 03:00:59 EDT
Description of problem:
When I attempted to dock mine laptop I have resumed from sleep a while ago, I got mentioned error in the journal and despite mouse was moving, I could not click and keybord was stuck as well. It "fixed" after few seconds when I disconnected laptop from the docking station.


Version-Release number of selected component (if applicable):
xorg-x11-server-Xorg-1.19.3-4.fc26.x86_64
kernel-4.11.9-300.fc26.x86_64
xfce4-session-4.12.1-10.fc26.x86_64

# lspci -k | grep -A 2 VGA 
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
	Subsystem: Lenovo Device 2210
	Kernel driver in use: i915


How reproducible:
rarely


Steps to Reproduce:
Very unclear, but I believe this could be it:
1. Dock & undock
2. Suspend & resume
3. Dock


Actual results:
Freeze until I undock, only mouse is moving


Expected results:
Should work
