Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: The driver version number in the ata_piix driver was not changed between Red Hat Enterprise Linux 4.7 and Red Hat Enterprise Linux 4.8, even though changes had been made between these releases. This could have prevented the driver from loading on systems that check driver versions, as this driver appeared older than it was. This update increases the driver version number.
