Are you overclocking, or not properly cooling, your CPU? My AMD 486
DX2-80 flakes out after a few hours, apparently from L1 cache corruption,
when not equipped with a heat sink and working fan. The signal 11 or
signal 6 or illegal instruction errors occur in random places, and while
I can eventually get the kernel to build with the CPU like this, odds
are there's errors anyway. So check your CPU... (my dx2-80 runs fine as
a dx4-100 or a dx2-100 with a heat sink and working fan).
