>Description:
I'm building a kernel (based on GENERIC, adding device enc) using this config file:

include GENERIC

ident           IPSEC

options         IPSEC
device          crypto
device          enc

After booting the resulting kernel I'm missing the enc device:

% ifconfig enc0
ifconfig: interface enc0 does not exist

dmesg shows this error message:

module_register: module enc already exists!
Module enc failed to register: 17

What's worse, if I'm actually setting up a tunnel, the kernel panics from trying to record stats on the missing enc device (null pointer dereference).

>How-To-Repeat:
see above.
>Fix:
Not a fix, but a workaround (since I don't need ses):

Add the following to the config file:

nodevice    ses
