I've had a considerable amount of instability the last few days, but I can't tell if its a hardware problem, or something introduced into the tree lately. It happens mostly when I'm in X, so I never see a panic, if there is one at all, and only 1 out of 3 times I'll get a coredump to go with it. I do have a coredump + debugging kernel for the above, if anyone wants it. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net /* FreeBSD: The fastest and most stable server OS on the planet.
