Replying myself, I guess there should be unlock before releasing the
periph at scsi_pass.c:

softc->flags |= PASS_FLAG_OPEN;
} else {

+ /* Device closes aren't symmetrical, so fix up the refcount */

cam_periph_release(periph);

}
cam_periph_unlock(periph);
I guess it needs to be committed.
Correct me if I'm wrong here.
