sata_sis driver does not detect SATA HD on P4S800D MB (2.6.6-rc1)

[lapo.pasqui]

Hi all,
I've tried everything to make my HD being detected by the sata_sis driver.
I've googled around and I notice there are no succesfully stories with the sata_driver and the P4S800D  MB.

Whilst there are no problem with the sis964 chipset  in general, a few complain some difficulties with the MB P4S800D.

I'm confident the HW is set up correctly (winXP is working).
Whem the driver is probing the HW, it always get this 

ata1: no device found (phy stat 8276fffe)

Looking at the code, it looks like the SATA status register never gets cleared.

I'm using the version 2.6.6-rc1 version of the kernel and this is what I get
(I also enabled the "Driver Core verbose debug messages")

cat /var/log/messages

Below is my HD description
MB P4S800D
SATA controller SIS 964/180
SATA HD MAXTOR D.MaxPlus9 6Y160P0
3 IDE devices

I'm not part of this mailing list so, please, if you whish, CC me to this address
lapo.pasqui@xxxxxxxx

Could it be a Mother board related issue?
Can somebody help? Can someone provide me with a datasheet for the SIS 964 chip and or the meaning of the 0x8276fffe value for the register?
I would like to help (and to be helped ;)

Thanks a lot
  Lapo
