I assume it's IRQ 19. cat /proc/interrupts doesn't show IRQ21 at all when uhci isn't loaded. IRQ 19 being shared with 4 IDE controllers that controls my hard drives, that's hard to isolate interrupts counts due to USB activity from interrupts counts due to disks activity... -- Michel Bouissou <[EMAIL PROTECTED]> OpenPGP ID 0xDDE8AC6E - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
