>Description:
On installation of 8.0-RELEASE (booting from cd) or after update via freebsd-update (from 7.2-RELEASE), the two sata hard disks are not detected. They work fine on 7.2-RELEASE.

Also there is some problem with ATA dma, which I managed to work around by setting hw.ata.ata_dma=0 and hw.ata.atapi_dma=0 at boot prompt, and USB 2.0, which i also worked around by disabling on the BIOS.
>How-To-Repeat:
Try to install 8.0-RELEASE or upgrade from 7.2-RELEASE.
