 Hello,
 
 You need to look in the developers-handbook (http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug.html)
 for more information about this topic. Hopefully you have serial access or something to get into the Debugger. If not
 you might want to try and dump any panics to the disk (as mentioned in the dev-handbook). If that all is not possible
 I hate to say this but: then you are on your own, we need -a lot more- information before we can actually do anything
 with this (in that case: sorry).
 
 Cheers
 remko
