Good, but as I have said, I am using 2.6.24.5 or below. According
to Google the patch was included in 2.6.25-rc3 so I am out of luck.

I tried 'libata.force=7.00:pio4' but it did not help.

And, nobody has so far asnwered my post with
Subject: 2.6.25: pata_marvell/ahci/libata regression: ata7: SATA link down (SStatus 0 SControl 300)

Basically, I cannot boot with 2.6.25. So I am stuck. Please
push the libata.force patch into 2.6.24 tree
(http://www.mail-archive.com/linux-ide@vger.kernel.org/msg15454.html).
Currently I can only use libata.dma=0.
