--- Comment #8 from Richard Scheffenegger <rscheff@freebsd.org> ---
https://reviews.freebsd.org/D18985 (RFC6675 SACK rescue retransmission) is =
not
in 13.0-RC4, thus https://reviews.freebsd.org/D29315 (fixing a off-by one, =
NULL
pointer free, introduced above) should not play a role here...

https://reviews.freebsd.org/D29083 could also lead to a panic in tcp_output,
but should be in RC4... (checked in Mar08, RC4 was Mar29).

Why libkern.h:92 for tcp_do_segment in frame 11?

Any possibility to get the core? Or the full tcpcb of frame 11?
