Probably pCardInfo is NULL.
Looking at the pms driver source is making my stomach churn, but I don't
see anything obvious. The field is set during attach, so it shouldn't be
NULL when the intrhook runs. Do you have any other storage devices on
this box? If so, I would try to kldload the pms driver after you have
booted far enough to setup dumps (either that or setup remote kgdb).
