GDB has been uncooperative in getting a back trace. Attempting to
examine the core has yeilded "panicstr" symbol not found and then
warnings about cannot read symbols and registers "INVALID PTE" which
I gather means I need to copy down an entire screen full of code from
ddb to paper and then retype it or try kgdb. Here's what I have so far
by hand.
