I tried anyway and unfortunately it crashes as before. I filled a bug report (https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D197535) and marius@ is giving me a big help on it.

The one, fairly ugly workaround I've f= ound that makes it work well enough is disable tso ( i.e. ifconfig re0 down= && ifconfig re0 -tso && ifconfig re0 up ).
