I don't think it's related to the VFIO racing problem (you would see a different error, permission denied)

However, there are two i40e bugs that might be related:

https://bugzilla.redhat.com/show_bug.cgi?id=1494424

https://bugzilla.redhat.com/show_bug.cgi?id=1428571

I know that the second on that list is not currently resolved, even upstream.  Need to spend time with the first.
