Also *tcp means its stuck on lock tcp? if so, that'd be lock on
V_tcbinfo. I think?

tcp_subr.c has tcp_init() which calls
in_pcbinfo_init(&V_tcbinfo, "tcp", &V_tcb, hashsize, hashsize,
    "tcp_inpcb", tcp_inpcb_init, NULL, 0, IPI_HASHFIELDS_4TUPLE);

and "tcp" is the name used to initialise the lock inside
in_pcbinfo_init() with
INP_INFO_LOCK_INIT(pcbinfo, name); 

What exact svn rev are you on? Also do you have any local changes?

Cheers,
