System hangs booting after uhub2: 7 ports with 7 removable, self powered

Hi!

FreeBSD 12 hangs booting after exhausting "uhub2: 7 ports with 7 removable,
self powered"
This is with a VMware Workstation VM -- but real hardware behaves same.

I've tried to boot using save-mode combined with single user, but without
success: same again. The old kernel just does not boot anymore, because of
zfs-error 45. Any idea what could cause the system stall and wait forever
starting init?

BTW: booting verbose did not really help: same last message.
