SATA 3.0 vil kun køre 2.0

Hej alle,

Har netop bygget en ny nas4free server (FreeBSD 9.1RC3), der har
problemer med SATA 3.0. Kernen kan sagtes identificere diskene som SATA
3.0, men vil kun køre SATA 2.0. Nogen her med et bud på, hvad jeg kan
gøre?

Jeg har prøvet med hint.ahcich.X.sata_rev="3" i loader.conf

Specs.
