I have made some type of action plan for you: 1) Compile a kernel with the options mentioned by Kostik at http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kernel= debug-deadlocks.html 2) Set the sio flags to 0x80 of consoles on the local machine per http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kernel= debug-online-gdb.html 3)get a copy of DDD if you want to 4) start having fun
