suricata and ipv6 trouble

[kiokoman]

sometimes suricata make my he.net tunnel not working anymore, packet loss 100% running it as lageacy mode,interface is gif0, dmesg show gif0: loop detected, i need to restart pfsense to make it work but packet loss is around 5%, if i disable suricata on that interface the packet loss go back to 0%
pfsense is 2.5.0
suricata is 4.1.6_3 but i think it start happened in the last 2 month
network card is intel i350-4 wan/henet tunnel and X550-t for lan/vlan

I noticed both Suricata 4.1.6_2, and 4.1.6_3 caused a crash report to be generated...I am also on pfSense 2.5 and dual Intel i350.
