Yenta + sata_sil + 2.6.30.8 fails because dma_ops==NULL

Yenta + sata_sil + 2.6.30.8 fails because dma_ops==NULL

[roger blofeld]

Hi
 I have a powerbook G4 which has drives connected via a cardbus sata_sil. It is running fedora 11. It boots fine with 2.6.27.35-170.2.94.fc10.ppc, but with 2.6.30.8-64.fc11.ppc because of an error in the probe function of sata_sil.

 I have traced the problem to be the line in sata_sil.c function sil_init_one

    rc = pci_set_dma_mask(pdev, ATA_DMA_MASK);

which returns -5 (-EIO) because 

 get_dma_ops(&pdev->dev);

returns NULL.

I looked at the diffs to sata_sil.c between these kernel revs and didn't see the problem. Seems to be something at a higher level changed.

Any ideas where I should look or how to find the real cause?

Thanks

P.S., on the working kernel lspci gives:
