Subject: SB600 and SATA disk in 2.6.21-rc5

Ubuntu 6.10  with kernel version 2.6.21-rc5 compiled with ahci support

I have a MSI K9AGM motherboard that ships with four SB600 SATA ports but 
when the kernel is booting it shows some errors and the SATA disk is not 
detected.

Here is what dmesg throws:

dmesg:

I attach the output of the lshw lspci -vvv and dmesg commands (all three 
of them executed as root).
