Bad hardware | bad memory | over-temperature | power-supply problem (including irregular mains power). Does it reliably compile other things ? One of my machines is an AMD Phenom of some sort - it has always had a tendency to segfault, possibly a BIOS problem, dropping the caches with echo 3 >/proc/sys/vm_drop_caches *mostly* helps - before I added that to my bootscripts, I used to find that using make -j3 instead of make -j4 was more reliable (somebody else also found that on a phenom). For memory, memtest86+ : many motherboards will NOT run for more than a few minutes with the "all cores" (F2) option - but if it locks up within 5 minutes you should reboot, select that again, then immediately use the option to configure it and choose round-robin or sequential for cores. Leave it running for a few hours, checking it from time to time. At one time, over-temperature used to be a common problem, with gummed-up fans - modern hardware tends to throttle the CPU if the temperature goes up. But if the BIOS lets you see temperatures, check them. Oh, and overclocking can cause this. And sometimes, it's just one of those things (alpha particles ?) and works fine next time. ĸen -- `I shall take my mountains', said Lu-Tze. `The climate will be good for them.' -- Small Gods -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
