Is the kernel build date an accurate reflection of the source code version it 
is being used with?  Could you let me know what file revisions are in use for 
uipc_socket.c, uipc_sockbuf2.c, uipc_syscalls.c, tcp_usrreq.c, tcp_input.c, 
tcp_subr.c?  Could you print *sb in frame #4, *so in frame #7, *tp in frame 
$5, and *inp in #5 (if defined) -- otherwise, (struct inpcb *)so->so_pcb, if 
non-NULL, in frame #6.
