If it doesn't, don't say it isn't memory... AMD-K6/2 systems are quirky with regard to RAM. Hopefully, you have a deep and wide spare parts pile to try different RAM in the things until you find something that works in the machine. Or, as is often the case on these things, you can slow down the bus speed of the processor (and sometimes, partly compensate by cranking the multiplier) and solve these problems. Failing that, try 133MHz RAM. I'm not sure what the exact source of the problem is, but it's common. It's not so much bad RAM as it is a quirky memory system. I've got a slightly similar machine here which took four or five restarts to get a complete custom kernel built for (which was needed for a driver not in GENERIC), but once running, it is pretty solid. I won't even try to build a system with it until I get around to slowing it down/putting better RAM in it. Nick.
