Re: Panic in socreate (Re: override for mpd)
Well, this is one for Jeff. Proto 47 must be something that is being
dynamically created. The crash is occuring here in socreate():
if (proto)
prp = pffindproto(dom, proto, type);
else
prp = pffindtype(dom, type);
if (prp == 0 || prp->pr_usrreqs->pru_attach == 0)
return (EPROTONOSUPPORT);
My assumption is that prp->pr_usrreqs is NULL. Jeff?
