And to silence it I had to enable the channel (using an IRQ), with no devices on it. it's gonna be a chatterbox, and the question is if the system can work with a shortage of up to 2 IRQs (irq 14 = primary IDE, irq 15 = secondary IDE) Especially early 586 and 686 classes I saw that often. Would you try enabling the IDE channels and see if the IRQ storms stop? --TJ _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
