Are you sure about bad memory?
Single-bit errors will be corrected; double-bit errors will generate NMI. You can also find memory errors with an exerciser. Unfortunately, trusty memtest86 bombs on my ServerWorks machine. Instead I use
http://www.qcc.sk.ca/~charlesc/software/memtester/
which runs in user-mode. I diagnosed thermal problems by running this utility. Within 3 minutes of cold start, it raised main memory temperature sufficiently to induce a hard error, which was detected simultaneously by it and the hardware (NMI taken by kernel).
Can you recommend one of your (shorter) tests for me to try? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
