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). -- John Baldwin _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
