Bug Description

I recently upgraded to artful (xenial -> zesty -> artful).

Now when I plug in my docking station I see this[1] in syslog and no network device appear.

The docking station is a ThinkPad OneLink+ Dock, my laptop a ThinkPad X1 Carbon 4th gen.

Does it work on Zesty kernel? You can still pick old kernel in GRUB menu.

@kaihengfeng, which kernel would that be? In grub I only see (taken from "dpkg --list | grep linux-image | grep ii"):
  - linux-image-4.12.0-11-generic
  - linux-image-4.13.0-041300rc6-generic

I take it I would have to install a previous kernel to check this one out?

I guess it works on Zesty?

Download and install Linux 4.10 from [1]

If 4.10 also has this issue, try 4.9, 4.8, ... in descending order.
