In your working dmesg the disks are controlled by ata_piix,
but you've disabled CONFIG_ATA_PIIX in the config you're trying.
So it's not surprising that you can't boot.

1) re-enable CONFIG_ATA_PIIX and disable CONFIG_IDE
or
2) go into the bios and change the option that says whether to run
   the ATA controller in legacy/compatible mode or enhanced/ahci mode,
   you want ahci mode
