Hmmm.  If you post your dmesg, lspci, and config, I'll be happy to compare
to my setup.  It might be something as simple as the Marvell driver loading
first and claiming the device.

The relevant part of my dmesg looks like this:

[    4.802703] ahci 0000:06:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
[    4.806351] ahci 0000:06:00.0: controller can't do NCQ, turning off CAP_NCQ

The Marvell driver never gets a chance to claim my device, as it is disabled in
my kernel config.  If you are using modules, you might want to blacklist "sata_mv".

If you are using modules from an initramfs, you might need to update your
initramfs, too.
