I'm not seeing any error messages in dmesg when attempting to start.  When
I do modprobe vfio-pci I do see:
VFIO - User Level meta-driver version: 0.3

It wouldn't suprise me if it was a hardware problem.  The motherboard is a
SuperMicro X9DRD-iF with a version 1.0 firmware.  I've seen some flakiness
with another SuperMicro motherboard when intel_iommu=on is set.

Thanks for the help
