with recent kernels I'm seeing this BUG - triggered by racoon - at boot:

Does it triggers after succesfull boot if you do

    rmmod af_key; modprobe af_key

a couple of times?

Post .config, just in case.

I am looking at ipsec_pfkey_init()

We call sock_register(&pfkey_family_ops) before pfkey_net_id being
initialized (by the call to register_pernet_subsys(&pfkey_net_ops);

As soon as sock_register(&pfkey_family_ops) is done, another thread can
open a socket and call pfkey_create()  -> crash

We should change order of initializations somehow
