Plus userland tools cannot report exactly what is wrong. memtest86 is a nice dos tool that helps in that case. > I believe that the regular suggestion is to try a "make world" > with half of your regular memory installed.

I removed all the SIMMs and gave the motherboard a big amount of air to get rid of the dust. Then I inserted the SIMMs again and now everything seems to be fine. "make world" and building a kernel worked without any problems. Thanks for all the hints.
