I power on my FreeBSD 6.0 Release system every morning and within 20 minutes, the kernel panics. Then it reboots and I never see a panic again as long as my system stays powered. It is almost always because of a page fault. From doing a backtrace on the dumps from 30+ seperate panics over the last couple of months, the instruction pointer is always at a different code location. So, it's certainly some kind of hardware issue, but the behavior of never having a kernel panic happen after a reboot, makes me think that a part of the hardware is not getting fully powered up and initialized before the kernel begins to load. Is there a BIOS setting to slow things down? Or maybe a kernel parameter to tweak for greater hardware fault tolerance? I ran memtest86 for a couple of days (the recommended 64 passes) with no errors. I realize that this test could possibly result in a false negative, but I don't want to run out and buy a new mobo and RAM if that isn't the problem. My hardware is: mobo: ABIT KX7-333 with VIA Apollo KT 333 chipset CPU: AMD Athlon XP 2000+ (1667 Mhz) Memory: Generic PC2700 - 133 DDR The video, sound, and NIC cards have already been factored out of the problem. Thanks for any advice. Jon
