You're most likely missing some key components in specifying your
disk controller.
Do you have SCSI, SATA, PATA? If you have SCSI/SATA, did you perhaps
install your system with GEOM enabled?
Booting into the backup kernel (single user mode), will be extremely
helpful in determining your issue, in particular what disk configuration
you're using.
