What am I supposed to see when there is a parity error on the main memory? I have a few memory modules I suspect to be bad, so I put them (256MB total) in our package building machine and tried a "make world", and got one "kernel page fault" (or something like that) and two lockups (no message on console). I disabled parity check in the BIOS, and world aborted once with a sh seg-faulting and once with a syntax error from make. At this point, I think it is pretty clear that the memory's at fault, but shouldn't I see some "NMI" type messages? (If I grepped correctly, it should be the "NMI indicates hardware failure" at line 265 in /sys/i386/i386/trap.c.) This is with a P6-200 (not overclocked) on an Intel Venus motherboard. Satoshi
