Hmm.. can you try that but with rte_kni left out completely? KNI hooks 
into the Linux network stack and think it at the least needs eliminating 
as a casual factor. Can you also try using uio_pci_generic rather than 
igb_uio?

Those aside, I'm suspecting driver issues, so seeing if I can get one of 
the driver test guys to have a look at this..
