i suppose that it's because the chipset isn't fully supported just yet.
Please post more information... Did you follow the guide and are you running the guide's kernel? Or what is your setup? The other possibility is that your harddrive just doesn't support DMA (though that is unlikely). As root, type dmesg and look through the output to see how the nforce2 ide driver got initialized.
