Yeah, that's one of those controllers I think. But I can't tell from
the bit of the dmesg you posted exactly what's going on. Can you post
a full boot log from having the card installed and some drive attached
(by putting the boot drive on another controller for example)?

Yes, the error is here: (its towards the bottom)

The system does not boot when the SSD is on that SATA controller.
The error we were trying to get earlier (kernel panic)-- I cannot reproduce
that anymore after adding nouveau for whatever reason.
So to re-cap it boots now with nothing connected to the controller but the
controller is non-workable/useless, as shown above.
When you put the SSD on it, it cannot mount rootfs.
