There's information about how to do kernel debugging at http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug.html But essentially panic() is called in kernel code when something wrong is detected so the system can stop whatever it's doing. doadump() just dumps the contents of memory to disk. -- Bruce Cran
