penalvch,

I just tried using the added IOMMU to my linux string as per the link above:
"iommu=soft swiotlb=131072"

Of course with "nomodeset" it never fails. I then remove "nomodeset" but kept "iommu=soft swiotlb=131072", and it never fails ( or hasn't yet).

Apparently newer boards have the IOMMU on the BIOS, my Narra6 does not.

Can the current nouveau compensate for the lack of no hardware IOMMU?

What exactly does this prove?
