Cool, perhaps if you provide some interesting information, someone _else_ will know how to interpret it. :-) First, we make some assumptions here: 1) When you configured your kernel, you did ``config -g'' for debugging support. 2) Hopefully, your crash isn't happening inside a kld. That's icky. For this situation, try to limit the number of kld's you use. gdb -k /path/to/kernel.debug /var/crash/vmcore.0 Gdb should tell you about the panic. You can then issue the command ``back'' at the GDB prompt to get a backtrace. Then cut'n'paste everything that follows the gdb copyright notice. :-) Ciao, Sheldon.
