I've been trying to anything useful after the SMAP printed out, and have failed. I assume that because of the place where the system is throwing a panic. Here is the SMAP output, I had to capture it twice to get it all on the screen. http://people.freebsd.org/~sbruno/smap1.png http://people.freebsd.org/~sbruno/smap2.png Immediately after, it jumps into the panic. I assume that this means more to you folks than it means to me. I'm still working on the printf. sean
