Yeah I started seeing this on one of my machines too, the
assertion is:

WARN_ON(newsk->sk_state == TCP_SYN_RECV);

I wonder if some of the refactorings we did to allow per-route
SACK/DSACK/etc. controls messed some sequence of state changes
on TCP sockets. But I can't find anything obvious in those
commits.
