Thank you to members of this list who have gotten me through a couple of serious issues. I have another one.
My system reboots at seemingly random times. Usually, this happens during keyboard or mouse input. I have been using kernel 2.6.30-r2. Often this happens when using firefox, but not exclusively. When I checked my machine, it had an uptime of nearly 4 hours after the last reboot, when I had not logged in. However, after logging in, I experienced two reboots in rapid succession. Interestingly, after I recompiled the kernel, enabling more modules of I2C stuff, to enable hardware monitoring for my Motherboard, the system has seemed to become less stable, and reboots readily. I usually use nvidia non-freedom drivers. I am now typing with the x11 drivers, and the system has not rebooted. I am now also using 2.6.29-r5. Once such things happened to me because I had a file with a filename starting with "_" in my filesystem. Everytime I started nautilus, firefox, or epiphany, the system would crash. This was some long time ago. I have three SATA drives installed, with a plethora of partitions. I am not sure where to look in logs to look for evidence of problems. May I set up the system to trap for such useful information? Alan Davis "...can the human soul be glimpsed through a microscope? Maybe, but you'd definitely need one of those very good ones with two eyepieces." -- Woody Allen, quoted by B. A. Palevitz
