I can apply this patch to test.

I don't think that's the issue - plain rc7 doesn't trigger the issue. Only if I merge tip/master in it happens. And there are no AMD iommu patches in tip/master since Joerg doesn't send stuff through tip anymore.

I still think the issue is in tip/master. I'm currently trying to reproduce on another box so that I can bisect it. (Bisecting on my workstation is always nasty :-\).
Thanks.
