What do you mean by this? I've been commenting on this issue in the past and I thought we agreed that this is no issue of the IOMMU driver. It it were, bisection should lead to a commit that breaks it, but there are no commits between v3.18 and v3.19 in the AMD IOMMU driver touching the DMA-API path.
