the problem is, that the machine ran without any problem until I
upgraded to kernel version 2.4.18. Originally I used the kernel which
was provided by the SuSE 8.0-CDs (2.4.18-4GB). Later I compiled my own
kernel, I upgraded to 2.4.19 but nothing helped.

I think it's not very likely that the problem is due to a hardware
problem as the first oops I ever got (after several years of happy
Linuxing) happened at the day I upgraded to 2.4.18-4GB and it never
stopped since then. I had memtest86 running once for several hours
which reported no problem.

I do (2.4.19). BTW, I don't have any special devices running (serial
mouse, ATA CD-ROM, SB16 Soundcard, Matrox Mystique Graphics-Card, the
streamer I have and which works smoothlessly is normally not activated
as the corresponding modules are not loaded).

I can't find any regularity in when it happens.

cat /proc/pci

What makes me wonder is the message from Sep 16 saying:
Sep 16 14:31:18 erde kernel: kernel BUG at page_alloc.c:206!

Thanks for your suggestions. I hope we can find the problem.
