I have seen similar symptoms on a different system.  That problem was due
to a long cable connected to the port, but no peripheral attatched to the
other end.  In effect, it acted like an antenna.  The noise induced on
the line caused repetitive interrupts to the card, which caused to card
f/w to stay in a loop, appearing to be hung.
