Multiport cards' operation problem on 5.0-RELEASE

Is anything actually broken? The above message is only to help diagnose
non-working interrupts. It is printed if interrupts are broken at
probe time. Interrupts might be broken at probe time but work later.

The new configuration seems to be OK, but is different (the master port
is 4 instead of 2).

Something unsorted sio10-sio11. All the sio ports are in numerical
order in hints but are in lexical order for probes. This shouldn't
matter, but the code that is supposed to give order independence was
broken a long time ago and never fixed (it is inside `#if 0' in both
RELENG_4 and -current).

I don't see how this can be fatal or give misbehaviour much different
from in RELENG_4. I would have expected the "not in bitmap" warning
more consistently. You seem to have accidentally avoided the disordering
of sio10-sio11 in RELENG_4 by only using 1-digit port numbers. Try
deleting sio2-sio3 from hints and moving sio4-sio11 down to sio2-9 to
get the same configuration as in RELENG_4. Try to duplicate the problem
with RELENG_4 by misconfiguring to get -current's strange probe order.
