gdb is unable to walk the stack. it is unable to determine the start of some function(s). May be a call back by pointer that went sideways? (My experience is more with proprietary hardware debuggers, so maybe I missed something). I do not have dnsmasq installed. odhcpd does all dhcp. This seems to happen immediately on the first IP4 request.
