EDAC i5000 NON-FATAL ERRORs on HP ProLiant Hardware

If you're seeing messages like 'EDAC i5000 NON-FATAL ERROR' in your kernel.log, and that is on HP ProLiant hardware (DL360 G5 in this case), take them seriously and PANIC ^W act immediately. (These messages are neither a kernel bug nor a hardware bug, but the plain truth.)

Just had a machine panic with an NMI today, and we've delayed ^W ignored the kernel messages for a few days...

Causes could probably be faulty RAM, faulty system board, or something else. If you don't get a lit 'memory faulty' LED, the IML will helpfully save a bit of info when an NMI occours, so you at least have something to tell HP.
