If i used 'config -g' when building my kernel, would that give more informative crashdumps? How about doing something else in kgdb? I've tried putting DDB in the kernel, but had no clue how to use it, so finally started doing crashdumps after redesigning my filesystems. Next time this happens maybe I'll be able to have what it takes to actually help. :-) -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net /* FreeBSD: The fastest and most stable server OS on the planet.
