LSB Version: core-9.20170808ubuntu1-noarch:printing-9.20170808ubuntu1-noarch:security-9.20170808ubuntu1-noarch
Distributor ID: LinuxMint
Description: Linux Mint 19 Tara
Release: 19
Codename: tara

Ubuntu 18.04
ThinkPad T460p

I reject the dock and want to use the dock again.
System hang, usb doesn't work, displays doesn't work.
Nothing but the ethernet connection at the dock is working.

The ThinkPad is working again, if I reject the dock.
But to use the dock again, I need to restart the laptop.

But I can reject the dock and plugin it again, while running the ThinkPad in Standby.
Weird.

I attached the dmesg and lspci logs.
