I can confirm this issue with Eoan Ermine (5.3.0-19-generic). I tried
disabling AppArmor (security_driver=none), but my laptop still locks up
at the Windows login screen (Windows 10).
Using the virtio NIC does work around the problem though.

I've been able to re-create the same issue using mainline
(5.3.9-050309-generic). Has anybody bisected kernel versions yet?
