Hi,
Do you have the complete backtrace for this panic?
Do you have any modules under /boot/modules, which are not up to date?
Does the same happen with audio/oss under 10.x ?

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?
