This is where the block diagram showing the socket and I/O slot connections would be useful. For the interrupts over a given interval, one can take snapshots at either end of the interval and then run them through beforeafter: ftp://ftp.cup.hp.com/dist/networking/tools/ I think that collectl might have something there too. I guess the addresses in use weren't sufficient to get interrupts spread across all 24 IRQ's. rick jones -- 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/ | |||||||||
