There are two different methods depending if your running 10.1.x or
10.2(prerelease)
In both cases you will have to generate your symbols as "relocatable".
10.1.x kmodsyms or 10.2: kextload.
Then you have to load(in the debugger) your symbol at the specific address
you see in the panic.
See in the Darwin dev list for a subject:
How to read a backtrace/kernel panic
It will give you a pretty good start.
If your kext is not required at boot, you can load it manually after boot to
see if your crash is a boot-time problem.
Hope to help
