Hov can i collect enought info about possible reasons? Pardon the "me too", but ... me too. With high frequency, I get a spontaneous reboot when trying to "make buildworld" after a fresh install of 4.0-RELEASE. Subsequent buildworlds dump core on either signal 10 or signal 11. A plain "make" will sometimes succeed, sometimes coredump with sig 10 or 11. The coredumps seem to happen at random locations in the build. This is with GENERIC or custom kernel, with or without UDMA turned on in the BIOS (the disk is UDMA33-capable), with or without go-fast BIOS options. I built the custom kernel with the -g config flag, but I don't know how to do post- mortems on core dumps. (I'll be glad to provide them to those who can deciper them). Happens in single and multi-user mode. Happens even immediately after a fresh minimalist install (no X, no ppp, no mouse, no linux emulation, completely new filesystem, yanked out the sound card and net card, leaving only the (IDE) modem). I thought that upgrading to 4.0-STABLE might help, but after cvsupping /usr/src, the same kind of errors occurred when compiling. So, no luck there. Happens on two similarly configured systems: K6-2 450MHz CPU, 64 or 128Mb Kingston PC-100 ValueRAM, FIC PA-2013 motherboard. One power supply is generic, the other is PC Power and Cooling. Award BIOS. (Speaking of BIOS, is there a FAQ anywhere for "My BIOS is from vendor XXXX. How should I set the options for best stability[speed] under FreeBSD?").
