Are you able to get the kernel backtrace from the console when it crashes? Most likely this is a regression in upstream Linux for the kernel that you are seeing the problem. Can you provide more details? Eg, where did you get your 4.6 kernel from? What is the full "uname -r" version for it? What .config was used when compiling it? Are you able to also try other versions, eg 4.4 or 4.9? _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
