I'll have to try this on my K6/2-400 [1] at work. I've been suspecting bad memory, but making the memory timings more aggresive didn't seem to affect anything. I could do make -j20 -l10 on a full GNU tools compile concurrently with a kernel compile and not have any problems. However, all the times when I did get a sig11, I was running the GIMPS [2] mprime program, which makes heavy use of the FPU.
I'll try upping my voltage a notch and let the list know what happens.
