on which platform?

cause, right now, if there's a stray interrupt we disable the
irq line if the interrut disable function is hooked to
ie_disab:

kern_intr.c::intr_event_handle():

        ...
        if (thread & FILTER_HANDLED) {
                if (ie->ie_eoi != NULL)
                        ie->ie_eoi(ie->ie_source);
        } else {
                if (ie->ie_disab != NULL)
                        ie->ie_disab(ie->ie_source);
        }
        ...

bye,
P.
