One last tidbit. I finally figured out what the IDE controller was and why it was loading and being controlled by ata_piix. This board is an Intel vPro board and it supports IDE redirection over LAN. Basically at the firmware level it lets be remote mount an ISO image as if it was a locally connected CD-ROM drive.

This virtual IDE CD-ROM drive is what is connected to the controller that ata_piix is driving. So the system was behaving as expected outside of the very slow boot.

So in summary. all that is needed to fix this bug is to change CONFIG_SATA_AHCI= to 'y' from 'm'.

I verified it by making the change in debian.master/config/amd64/config/config.flavour.*

I then rebuilt the lucid kernel, installed it and I am a happy ubuntu user again.
