    I've noticed some funkiness the last 1-2 times I rebooted by
STABLE-9 box as well where it will hang with ada+mfi/ZFS (two separate
pools), but I didn't think much of it at the time. I really don't like
rebooting that box all that often.
    I have another system that has just ada+ada/ZFS (two separate
pools) with approximately the same src version and it doesn't exhibit
the same issue (but I don't remember the last time I shut it down
cleanly because I've paniced the box screwing around with it a few
times), so while my gut feeling goes towards mfi being wonky or
another hardware difference between the two machines -- the root issue
could be (and probably is) something completely different.

Box that hanged a couple times:

Box that seems ok ;/..
