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.. Regards, ..Remy
