I managed to install the snapshot from CD and provoke
the panics with a manual ifconfig. Thus I could obtain
crash dumps, which I have sort-of analysed.

I've filed a PR with all the details (stack trace with
symbols, analysed some variables, etc): kern/58139
Please check it out:

Thanks for your help.

Best regards,
 Daniel
