Hello.
I have a sil3132 pci-e card and a DB-88F6282-A-BP(Marvell development
board based on Arm9).
I compiled sata_sil24 driver as a module with a cross-compiler.
But, when loading the driver, qc timeout error was occurred during
ata_read_dev_id.
What is wrong, IRQ or DMA ?
looks to me this is DMA issue, can you force pio mode? you can do that
by adding "libata.dma=0" to the kernel command line.

I have 2.6.31.8
Dear saeed,
I excuted libata.dma=0 through "$modprobe libata dma=0"
Then I excuted "$modprobe sata_sil24"
But, result is same as before.
I think sata_sil24 supports only dma not pio, right?
Thank you.
