    Indeed, I changed to ipvlan and no hard locks yet.

    Also seeing possibly a related issue. Hard freeze, no response to ping at all. Started saving syslog to USB and finally got a useful trace. Lenovo ThinkServer TS140, Xeon E3-1226 v3. Going to migrate from macvlan to see if it mitigates freezing.

    I'm seeing the same issue. @Timm, libvirt is using it for one of its bridges.
