>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:

Seems the bug managed to make it into -stable recently.
>How-To-Repeat:
