Comment 40 for bug 1488426

FYI still happening to me on 18.04 with HWE kernel,
similar behavior as #38: kworker with steady high
cpu usage after un-docking, re-docking didn't solve
it tho.

kernel: 4.18.0-15-generic
hardware: Thinkpad x270, Thinkpad Ultra Dock, network: enp0s31f6 (dock eth) and wlp3s0 up
