Odd, it's against stock head, so I don't know why it would have failed to apply. > I have rebooted the dell and it seems happy with the new patch (msi > disabled.) Okay, good.

Can you try changing it to use MSI instead of MSI-X? Just edit the mfi_pci.c call and replace 'pci_alloc_msix' with 'pci_alloc_msi'. -- John Baldwin
