For Nick White: would you be able to supply the output you saw when your system hung (if this is already past mounting the real rootfs there could be old entries. journalctl --list-boots to see which and journalctl -b<number> to show logs from a previous boot).
Unfortunately we cannot see any hangs with VMs and reproduction of the various symptoms seems only be possible with luck and on laptop hardware. This could be something related to USB... Will try to follow some of the bread crumbs we got.
