So it looks like it is using logical flat mode and the interrupt was from IO-APIC. So most likely on your system after a successful boot, if you manually set the affinity of one of those SATA/PATA interrupts to a specific logical cpu say 0, I think the interrupt still get routed to other logical cpu's. Can you confirm? thanks, suresh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
