I had a weird panic this morning, after the machine was up overnight (although not really doing anything). I have 'tail -f $HOME/.xsession-errors > /dev/console &' in my .xsession file, and when I logged out of windowmaker to replace it with the latest version, for some reason the script that's supposed to run that kills that job on the way out didn't run. When I started the new wm I noticed that I had two tail's running, so I tried to kill one. As soon as I typed 'kill ' in the xterm the system locked up, and eventually panic'ed and rebooted. To add to the excitement I changed my kernel debugging options last night to include WITNESS. I now have WITNESS and INVARIANTS, no DIAGNOSTIC. I have a UP system, Celeron 300A on an Asus P2B motherboard. Here's what I got from kgdb, I have the core and debug kernel if anyone wants more data. Enjoy, Doug -- "Pain heals. Chicks dig scars.
