What I saw was my KDE desktop stopped responding to events. Machine didn't respond to power switch. Unfortunately, that's all I know. In the past when I had bugs like this, I got a fairly extensive kernel error message, but this time the above is the only thing I saw. I have not had kernel bugs like this until I started running 2.6.20 on a new Kubuntu install. Same hardware, but Slackware and my own custom 2.6.19 kernel never crashed. Is there anything I can do, in case this happens again, to try and capture more information? -- shannon | An Irishman is never drunk as long as he can hold onto | one blade of grass and not fall off the face of the earth.
