Hi Kevin,

Can you post the output of “scripts/setup.sh status”?

This debug message is not complete and needs to be improved.  It is not enough for ioatdma to not be loaded – those PCI functions need to also be bound to uio_pci_generic or vfio-pci.  The command above will clarify if these functions have been bound correctly.
