--- Comment #6 from Mark Johnston <markj at FreeBSD.org> ---
We are crashing here:

1120 #ifdef VIMAGE                                                              
1121         if (V_netisr_enable[proto] == 0) {                                 
1122                 m_freem(m);                                                
1123                 return (ENOPROTOOPT);                                      
1124         }                                                                  
1125 #endif

I guess we are missing a CURVNET_SET() somewhere in netgraph?
