Comment 7 for bug 119640

Well, all my testing has been with gutsy gibbon, downloaded a few days ago. The problem seems to be that the ata_piix module grabs the ide channel without being able to drive them. This page http://www.thinkwiki.org/wiki/Problems_with_SATA_and_Linux suggest several workaround, of which I tested (on the busybox line, so no install was possible) unloading ata_piix, load ide_generic and then load ata_piix. That seemed to work, but I don't know how to resume the installation after doing that bit of magic.
