[prior incomplete message was sent accidently] Have a relatively recent HP DL160 G5 incorporating the Seaburg 5400 chipset. Appears the 5400 is a MCM including a 631xESB/632xESB I/O controller. Running kernel 2.6.27.1. Latest HP BIOS. Strangely the SATA controller seems to be reporting that it can only run at 1.5 Gbps instead of 3 Gbps. ahci 0000:00:1f.2: version 3.0 ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) -> IRQ 19 ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 6 ports 1.5 Gbps 0x3f impl SATA mode ahci 0000:00:1f.2: flags: 64bit ncq pm led slum part ahci 0000:00:1f.2: setting latency timer to 64 Looked at the AHCI specification and Intel datasheets for both the 5400 and the 631xESB/632xESB. The latter shows the register but does not include 3 Gpbs in the enumeration. SATA-II support is stated in general for the device however. The SATA links all are reported as running at 1.5 Gbps. Definitely did pull the rate-limit jumpers off the Seagate ES.2 drives. details: http://binnacle.cx/file/ahci_seaburg_downspeed_dmesg.txt http://binnacle.cx/file/ahci_seaburg_downspeed_dmidecode.txt http://binnacle.cx/file/ahci_seaburg_downspeed_hdparm-I.txt http://binnacle.cx/file/ahci_seaburg_downspeed_lspci-vv.txt -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
