Ah. OK.
It shouldn't do that. It should be handling things just fine. When
IRQ 9 is used, do you find that it locks up
a) if the card is in the machine on boot?
b) The moment the card is inserted?
c) A few seconds later during the probe of the card (but
before the probe message prints)
d) After the probe/attach sequence on the card's first
interrupt?
And is this card in slot 0 or slot 1? And do pcic0 and pcic1 have the
same interrupt or a different interrupt?
