I have to ask since i do not know, but does the hardware INT lines have any relation with this issue? I have a motherboard where this (or a similar) issue seems to happen (compaq ml370 and can do both modes where it has 16 IRQ's and more than 16 IRQ's) In both modes this same issue happens (usb, ata1 and bge0 fires on packet received on bge0 or usb polling). I recently had usb removed to try to lessen the performance impact this only reduced the interrupt rate from 22 p/s to 12 p/s. In my case ata1 and uhci0 (i think it was uhci) both shared irq 15. irq15: ata1 20899728 12 irq29: bge0 20899895 12 I always understood this to be the effect of equipment sharing the same hardware INT lines. Can anyone tell me if it's the same issue and if it has anything to do with the hardware INT lines? Below is vmstat, pciconf and dmesg output. ---------------[ vmstat -i ]--------- interrupt total rate irq3: sio1 2 0 irq4: sio0 9 0 irq6: fdc0 15 0 irq8: rtc 215983081 128 irq13: npx0 1 0 irq14: ata0 68 0 irq15: ata1 20899728 12 irq29: bge0 20899895 12 irq30: ahc0 10801075 6 irq31: ahc1 15 0 irq0: clk 1687632823 1000 Total 1956216712 1159 ---------------[ dmesg ]-------------- Copyright (c) 1992-2005 The FreeBSD Project.
