Bug Description
Machine is Toshiba Qosmio G20 laptop with Intel 82801FBM (ICH6M) SATA Controller. Worked with Edgy with kernel versions up to 2.6.17-11. Upgraded to feisty using aptitude dist-upgrade and kernel 2.6.20-15 was installed which would not boot - system hangs. Later upgrade to 2-6-20-16 did not resolve. Attempted clean install from Feisty CD image, OK as live CD but disks not detected. Same with latest snapshop of Gutsy and with vanillla Debian Etch. Can install/reinstall Debian Sarge and Ubuntu Edgy OK from CDs.

I can confirm this bug on toshiba g20.
It seems that when ata_piix is loaded before ahci, ahci module will not see harddrives correctly.
This helps from initramfs shell:
rmmod ata_piix
rmmod ahci
modprobe ahci
exit
I resolved the problem by blacklisting ata_piix module in initrd image. It seems it is latter loaded correctly (latter in boot, when system already chrooted)
Also it seems it is duplicate of bug: #139790
