Sorry to reply to my own post.

I should clarify that I have only tried enabling some USB quirks
_after_ the problem has started, but my main problem is now that the
disk is 'stuck' in the computer.

Is there a trick to removing that drive now without causing a panic?

I've tried umount -f (hangs, but now mount doesn't show it mounted,
although newfs can't open for writing), followed by camcontrol eject
da0 (fails).
