dmesg after finally crashing at third unplug cycle

Recently I plugged a seldom-used TeVii S660 DVB-S2 Adapter into my laptop and
after undocking found a kernel oops.

I tracked this down to "Last working Kernel 4.17", even tried to bisect it but
was not successful (ended up in an obviously unrelated commit).
This is probably some kind of race condition, since reproducing in a KVM VM
(with usb passthroug) sometimes only crashes after a few tries. On real
hardware it crashes pretty reliably for me, this is why I prefer to test this
in a VM :-)

See attached dmesg of the oopsed kenrel.

I can try whatever you deem useful :-)
