Following suggestions from mav@ on the FreeBSD forums (
http://forums.freebsd.org/showthread.php?t=43238), I've discovered that the
problem was somehow caused by SWAP being enabled on the device which was
being unplugged. Considering that 'top' output indicated no swap was being
used, and that the system had nearly 63 GB unused memory at the time, I
would be surprised if anything was swapped.

Although the issue is not what I initially thought it was, I still believe
this is a problem which needs resolving, as a hdd dying for whatever reason
should not make a port unavailable for what seems like an arbitary period
of time. (I have not yet managed to make the port work again by any other
way than a reboot, but I only left the system running for up to 15 minutes)
