No, the interrupt code itself will handle shared interrupts (it will call all handlers). I think in practice that uart is setting INTR_EXCL or some such and/or uart doesn't set RF_SHAREABLE when allocating the IRQ. It is probably the latter. You could try just adding RF_SHAREABLE to the bus_alloc_resource_any() for the IRQ to uart and see if that fixes it. -- John Baldwin _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
