>From /sys/pccard.c:
static int
slot_suspend(void *arg)
{
struct slot *slt = arg;
/* This code stolen from pccard_event:card_removed */
if (slt->state == filled) {
int s = splhigh();
---> disable_slot(slt);
slt->state = suspend;
splx(s);
printf("Card disabled, slot %d\n", slt->slotnum);
}
----> slt->ctrl->disable(slt);
return (0);
}
Note the lines I point to. We disable the slot, as well as the
controller at suspend time. There isn't much more I could disable. :)
