The urio driver appears to call make_dev, discarding the returned dev_t,
and never bothers to call destroy_dev.
Although this is presumably broken, it did _work_ previously. however,
there is now a 'panic("don't do that");' call in make_dev (and
destroy_dev) to prevent duplicate calls, thus the machine will crash if
you attach/detach/re-attach a rio. This has been happing for quite a
while now, but I've never been bothered enough to actually try to fix it,
until now. :)
I have approximately no experience with FreeBSD device drivers, but I'm
currently attempting to see if I can figure out how the other u*.c files
handle detaching... any hints would be appreciated :)
