One more observations from my little experience:

Probably you have a SATA (Serial ATA) disk and you forgot to check the
module for that while configuring the kernel. OR probably, this is a
SCSI device and you have disabled SCSI support while kernel config.
Do make sure that you have enabled the module of the disk type you are using.

I agree this is not limited to SATA module - but I found that as most
happening error for me.
