  Please try to get at least a backtrace, withouth that probably nobody will 
be able to help you. The above information (ip_rcv_finish and ipt_do_table 
being present in the trace) is completely useless, as processing _any_ IPv4 
packet could lead to receiving such a backtrace...

  You could still try getting a backtrace with SysRq + P.
