So that's using the old IDE drivers. And the network and USB are sharing IRQ#11 with each other. If you are going to be using newer kernels like this (2.6.23+), then you might consider shifting those drives over to libata drivers. This involves a little bit of work -- building a kernel with libata and "ata_piix" built-in instead of the old IDE drivers, and then rearranging /etc/fstab to match the new device names (eg. /dev/sda instead of /dev/hda). But at this point libata is working much better than the old IDE stuff, and it really is worth moving things over if you can. Cheers
