Wmmm, there were much changes to tcp code for IPv6 support after Jan 5.

I reviewed tcp_setpersist related code and such problem not
seems to happen in correct state.
Might there be incorrect memory over writing?

Do you have any other date, such as *tt_persist value at
panic?

And is there any other person who experienced same kind of
problem and have any hints to diagnose this?

I'll again review my changes.

Thanks,
Yoshinobu Inoue
