We hit a problem with IOMMU with that. Disable until we have time to

Thanks for taking care of this Christian.
Actually I'm not that happy about this because it seems to point out
either a hardware problem or a software problem in the IOMMU driver.
I just don't have time to investigate further, so disabling it is the
least I can do.
Maybe add a reference to at
least one of the bug reports about this, but either way:
