--- Comment #11 from Richard Scheffenegger <rscheff@freebsd.org> ---
Two more question: Have you observed this type of panic once, or multiple
times?

how are net.inet.tcp.rfc6675_pipe and net.inet.tcp.do_prr set?

If this is repeatable in your environment, you may want to reenable sack, but
disable PRR (which is the new mechanism in 13). 

If this is repeatable, would you be willing to enable blackbox logging, or
alternatively a packet capture of what leads up to this event?
