Or a driver bug: Failing to clear the condition causing the interrupt before sending an end-of-interrupt notification to the device will cause it to re-assert the interrupt request. I've also seen it when a device configured for polling (and hence without an installed interrupt handler) decides to raise an interrupt and gets upset at the interrupt not being handled. -- Peter Jeremy _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
