When I removed the Highpoint 2-port SATA card and plugged it into the
motherboard, the system boots (plugged the SSD into the motherboard).
So if you use a HIGHPOINT 2-PORT SATA 6.0gbps card, do NOT enable IOMMU or
it will fail to initialize the Highpoint 2-port SATA controller card!
I also tried upgrading the BIOS (of the mobo, no diff)
I also tried just leaving the SATA card in and plugging it into the
motherboard (no diff)
Removed the Highpoint 2-port SATA card and then success, it would be nice to
use that card with IOMMU support though, is it just not compatible
(marvell-problem?) or is a driver bug?  Based on the pictures/etc sent
earlier?
