Would be great if you find the time to bisect the issue. To speed thing up you can test commit b67ad2f and use it as the bad one if it shows the same problem. As good commit you can use the v4.3 tag, this will only bisect in the iommu related changes which went into v4.4-rc1. If commit b67ad2f works for you, then please bisect between v4.3 and v4.4. Joerg
