Hi,
Since some time i get:

Does these messages impede "Device assignment with VFIO" testing?
My mobo is a Asus Sabertooth 990FX 1.0, there is some discussion on the forum:

I tried to assign a pcie Ethernet card about a year ago (no vfio) and
the result was a lockup.
I have not tried ever since.
If AMD-Vi is initialized w/o interrupt remapping, but otherwise works,
use the allow_unsafe_interrupts=1 module option to vfio_iommu_type1.
Thanks,
Alex
