There is something going on with USB in this release. My AMD X570 board 
is constantly having ports stop working, while a older AMD X399 board 
seems fine (maybe, there is an ATEN USB extender involved on the X570 
system)

I've only had time to do very rudimentary debugging, but reverting all 
usb and xhci related patches seems to have solved it, eg:

I might be able to narrow it down in a day or two.
