Bug Description

When notebook is in docking station the kernel crashes after bootup and logon in GDM.
If notebook is in standalone mode without any external devices connected everything works.

Tried to step back to Kernel 4.15.0-43-generic and everything works like a charm.

Release: 18.04

I see a problem that I think may be the same on a T470s. I don't know how to confirm if it's the same problem since my laptop crash when I lock the screen when the laptop is docked in a Lenovo dock. It started recently after upgrading the kernel.

I can confirm this with Lenovo X280, except that it happens on a USB-C connected monitor which has a builtin USB-hub (the monitor is the docking station). It makes the docking station unusable. In older kernels this setup used to work. I have multiple crashes like this.

I'm having the same issue on a Dell Latitude 5289 laptop connected to a dell USB-C dock with 2 external monitors, and USB keyboard and mouse (Razer Naga Chroma).

My computer will immediately lock up upon pressing Super + L to lock the screen when it's connected to the dock. When disconnected from the dock, it wakes up fine.

This is isolated to 4.15.0-44 for me as well. I am unable to replicate in 4.15.0-43.
