I booted with iommu=pt kernel parameter and i stopped getting these messages.
I am experimenting with pcie kvm pass-through, so i ended using that parameter.
Sadly the whole host freezes when i power on the guest, but that is outside of
this bug-report.

I don't think that was actually not 100% accurate.
