Thanks for your testing. The issue turned out to be an older bug, which
just got uncovered by these patches. I updated the branch at
git://git.kernel.org/pub/scm/linux/kernel/git/joro/linux.git
amd-iommu-iova
This branch boots now on my Kaveri and Carrizo system. Can you please
give it a test too?
Thanks,
Joerg
