    AFAIK this message says CPU got a spurious NMI. It does not kill the task,
    kernel logs this message and returns from NMI interrupt handler.

    What does cat /proc/interrupts tell you?

    NMI may be truly spurious or a hardware failure indication. Give your box
    an overnight run of memtest86.
