I had a similar problem on my K6-3. I would get three or four
undesireable signals of various kinds during every kernnel compile. I
also tried turning off page zeroing with no effect. A source and compiler
upgrade fixed the problem completely as far as I can tell (though I have
not tried building the world yet).
