Yes there are a lot of workarounds (see the 4 proposals below). igb_uio is an out-of-tree kernel module. We are replacing it with upstream modules uio_pci_generic or vfio. 1/ Try to disable igb_uio in your config (x86_64-native-linuxapp-gcc/.c= onfig): =09CONFIG_RTE_EAL_IGB_UIO=3Dn 2/ If you want igb_uio, you should upgrade your kernel 3/ If you want to keep this kernel, you can try an older DPDK version 4/ If you want to keep this kernel and this DPDK, you can try to fix =09the issue and submit a patch to dev@dpdk.org.
