Public bug reported:
happens each time on kernel 5.3.0-40 when I disconnect thunderbolt docking
station.
Does *not* happen on 5.3.0-28.
After it happens almost everything still works ok: the only malfunction I've
noticed is that after reconnecting the dock, USB devices (mouse, keyboard)
connected via the dock don't work at all. However monitor connected via the
dock still works fine.
Hardware essentials:
Dell Inc. XPS 13 9360/0D4J15, BIOS 2.13.0
Plugable TBT3-UDV Docking Station
Does not happen when disconnecting "simpler" devices like apple's usb-c
to hdmi/usb/usb-c adapter.
