>Description:
In the FAQ section 'For serious FreeBSD hackers only'
question 'Making the most of a kernel panic' we currently
ask for alphabetic-sorted output from nm(1).
When trying to debug the panic it is alot easier to find
the instruction address if the output is numeric-sorted.
>How-To-Repeat:
>Fix:
Tell the user to use 'nm -n /kernel.that....' instead.
