[CentOS] SATA errors in log

Hi,

I have a SATA PCIe 6Gbps 4 port controller card made by Startech. The 
kernel (Linux viz1 2.6.32-220.4.1.el6.x86_64) sees it as

  Marvell Technology Group Ltd. 88SE9123

I use it to provide extra SATA ports to a raid system.

The HD's are all "WD2003FYYS" and so run at 3Gbps on the 6Gbps controller.

However I am seeing lots of instances of errors like this

Vendor ID : 1b4b
Device ID : 9123

I tried to see what drivers were currently being used but the command 
below gave nothing

grep -i 1b4b /lib/modules/*/modules.alias | grep -i 9123

I have changed the card and cables but still get the same errors. I am 
wondering if the el6 kernel is using the correct drivers I checked 
"elrepo" against the "Vendor:Device ID pairing" and it also came up blank.

Any ideas would be much appreciated.

Regards,

Steve
