Subject: [2.6.20.15] CK804 / sata_nv: Reported link speed not as expected.
Hello, I am not on list so please CC me with any responses.
I recently switched to an nforce4 board and have been looking over my
dmesg output for any oddities. This is a Slackware 12.0 machine with a
custom 2.6.20.15 kernel.
As far as I know, the motherboard is an Nforce4 based (non-ultra/sli,
etc) board. The exact model is Foxconn (Winfast) NF4K8AB-RS (
http://www.foxconnchannel.com/EN-US/Product/motherboard_detail.aspx?ID=en-gb0000027
). It has the latest BIOS available applied.
The product documentation states the board only supports 4x SATA150
connectors and that seems to match the information on this page (
http://www.nvidia.com/page/nforce4_family.html ). Three of the disks
are Seagate drives and have the SATA150 clip jumper set. However when
I boot, the kernel output seems to show 2 of the 4 ports operating at
3 Gbps. Is this a known issue and/or something I can safely ignore?
dmesg, config and lspci output attached. Here is a snippet of the
output in question:
