There were a few things to do with IGMP packet checks which I rolled in to my last swathe of changes. If this is a purely IGMP related problem, those fixes should be enough to get going. On the other hand, you could try backing out the last few revs on ip_mroute.c where I've tried to clean up some of the legacy code and get it into modernity. I didn't turn up any problems with that code in my most recent testing (last March, when I committed them), but my testing was limited to my own LAN. The backtrace in the PR suggested a problem around m_freem(), this could be a problem with another call which uses the mbuf.
