Also, if you like your port multiplier to work much faster and stable - I would strongly suggest you to update to 8-STABLE (or wait forthcoming 8.1-RELEASE, if you prefer releases) and use new siis(4) driver for your SiI3132 SATA controller. Port Multiplier support in ata(4) driver left in embryo level and won't be improved. -- Alexander Motin
