Before this, you were booting from some other device,
and the sata_mv mostly worked for you there, right ?

Specifically, you wrote:

So at least that much should now be working much better for you.

I have not actually ever booted from a sata_mv controller yet,
so maybe there's still something peculiar about libata::sata_mv
early in the boot stages ?

I'm using sata_mv as a module here, but I *never* use initrd/initramfs images.
They just complicate things needlessly once I know my hardware config.
But it should work.  I'll try booting from a sata_mv drive here
on your board and see what's up.
