Incidentally, although I don't think it's relevant to Greg's problem,
there is a possible race in the IAA watchdog code.  If an IAA interrupt
does get lost but then an ordinary I/O completion interrupt occurs just
as the watchdog timer expires, the timer routine could get very
confused.  For instance, the "WARN_ON(!ehci->reclaim)" line might fire.
