Can you build a kernel that includes debugging information and read the ``Kernel Debugging'' chapter of the FreeBSD Developer's Handbook? After that, you should be able to get a crash dump from your kernel and post the information here. > i have linux background and used to ipchanes... but i'm new to ipfw > on freebsd. That's ok. The FreeBSD documentation for ipfw(8) will help :-) > in the rc.conf file the ipfw type is unknown which means that when > rc.firewall gets called there is no firewall rules set up... i > don't see how this will make the machine crash when i type: > # ipfw -a show > > i'm thinking of recompiling the kernel but not sure if this will > help.... Not just your kernel. That's not the way it works on FreeBSD. Please, when upgrading, read carefully the file /usr/src/UPDATING and follow the instructions it contains.
