Ok, from your output plus the nvalid magic number we can say that it seems
somewhat related to your HNA settings. A few more questions:
* In this case the batgat module is not involved and still it crashes ?!
* Is your network up & running ? Does batman receive messages from neighbor
nodes (you can track that via debug log 4) ?
* Does batman also crash in a disconnected environment ?

The log you just provided is not about a kernel crash - its "just" the batman
daemon. Are we hunting 2 different bugs ?

Ok, keep us posted.
