Isn't it possible to have more than one UART generate IRQ3 and have the driver ask each UART if it's got anything to do ? I don't know if this IRQ/polling setup would prevent ``fast interrupt'' handling though. -- Brian <brian@Awfulhak.org>, <brian@FreeBSD.org>, <brian@OpenBSD.org> <http://www.Awfulhak.org> Don't _EVER_ lose your sense of humour....
