I think it's a clue that the process that's runing when the panic occurs is ipfw (every time0 This machine has two network connections (beesides oopback). A fill time ehternet connection, and a dial on demand ppp link. The ppp link is brougth up when runing periodic daily, for reasosn I do not yet understand. # # BLACK -- BLACK kernel configuration file for FreeBSD/i386 # # For more information on this file, please read the handbook section on # Kernel Configuration Files: # # http://www.FreeBSD.org/handbook/kernelconfig-config.html # # The handbook is also available locally in /usr/share/doc/handbook # if you've installed the doc distribution, otherwise always see the # FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the # latest information. # # An exhaustive list of options and more detailed explanations of the # device lines is also present in the ./LINT configuration file.
