My suggestion, knowing nothing about the ataipcam code, would be to
add a line just after the "if", which says:
printf("ccb_h->target_id = %d\n", ccb_h->target_id);
Hmmm.. Thomas, how can ccb_h->target_id ever be less than 0 if
a target_id_t is typedef'ed to a u_int? Perhaps the test should be
if (softc->ata_ch && ccb_h->target_id != CAM_TARGET_WILDCARD) {
