IPV6 TCP6 Slow Connect

[Larry Rosenman]

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=206904

I've also posted lots of info to freebsd-net, and not gotten any 
response.

Summary:

Cable Modem-> EM0 on a pfSense Firewall (FreeBSD 10.1, pfSense 2.2.6)
               set to dhcp6, and ask for a /56 prefix

EM1->LAN, set to track interface, prefix id 0, radvd running advertising 
the 00 /64
LAN-> borg.lerctr.org using lagg0, SLAAC (rtsold).  Gets an address, 
icmp6 works, tcp6 times out.
     -> win10 SLAAC, tcp6 works fine, as does icmp6.

I seem to be able to CRASH -CURRENT by just rebooting the pfSense 
firewall.

What do I need to get to help get to the bottom of this?
