> How can I get it and save it too?

First you need to configure your kernel with DDB, see:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-online-ddb.html

and use the 'trace' command to obtain a backtrace once you get a panic.

I think the easiest way to save the trace is to obtain it from a serial
console, and save a transcript of the session on the terminal side.

Thomas.
