>Description:
If you try and use IPsec and an enc(4) device on 9.1 you get a panic. The encif structure isn't setup because the 'enc' device name clashes with another name in CAM. jhb@ found and fixed this in -current last year:

http://lists.freebsd.org/pipermail/freebsd-net/2012-October/033403.html

Seems the bug managed to make it into -stable recently.
>How-To-Repeat:
Use IPsec + enc(4) on 9.1.
>Fix:
See patch:
