What the heck is that?  Do you have some stupid legacy emulation enabled
in the BIOS or what is that doing.

This looks like ide-generic is playing with the port after ata_piix

Which kernel version is this?

If it is 2.6.24, then well, use something else, it seems to hate a lot
of intel chipsets.  2.6.22 or 2.6.25 seems fine.
