While as far as i know the particular machine has not been advertised as supporting 6 Gbps sata, i had expected the chipset to make use of it [1]. The controller device is a 1002:4391. I am using it with kernel 2.6.39-rc1 on an Intel SSD that supports 6 Gbps link speeds (as confirmed by hdparm). In sysfs, I read sata_spd as "3.0 Gbps" and both "sata_spd_limit" and "hw_sata_spd_limit" as "". On boot, the device comes up as: ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata1.00: ATA-8: INTEL SSDSC2MH120A2, PPG2, max UDMA/133 ata1.00: configured for UDMA/133 Any suggestions? thanks, gohai [1] http://ixbtlabs.com/articles3/mainboard/chipset-hudson-m1.html
