ata_piix 2.6.25 sata failure

[Matthieu CASTET]

Hi,

the 2.6.25 from debian fail to make work the second port. I got a "SATA 
link down (SStatus 61 Scontrol 30)" for ata2. ata1 got "SATA link up 3.0 
Gbps (SStatus 13 SControl 30)"
The 2.6.24 works [1]. But some previous kernel (IRRC 2.6.18) had the 
same problem, ie ata2 doesn't work.

My hardware is a intel ICH8[2]
