Hmm, I narrowed it down. It starts going havoc if there are more than 4 PCI cards inserted. If the fifth card is a PCI card, I get lots of errors and even lockups really soon, if the fifth card is an ISA card, i get less errors and I've only encountered one lockup until now. I've two NICs and two graphic-cards (all PCI), ide-controller onboard and scsi controller onboard. Is this behaviour something that might be expected with this kind of setup or is it a sign of defective/failing hardware (buggy/broken southbridge, as Chuck suggested)? TIA :-) Bye Marc
