Do you have a more detailed message?  Was this during boot or afterwards?  If 
it was after boot building a kernel with debugging and getting a crashdump 
would be most useful.  If it was during boot, knowing the last few messages 
before the crash (and the first 2-3 frames from a stack trace in ddb) would 
be most helpful.
