- It simply means what it says: the processor got a NMI (nonmaskable
- interrupt), but as there is nothing you can really do about it, linux
- essentially ignores it apart from telling the user about it with a
- printk().
-
- NMI's generally get generated by either memory parity errors or by
- special hardware (power-saving features etc). Linux tries to disable
- NMI completely because it can't handle it anyway, but it seems some
- motherboards let it through anyway (or then I do the disabling
- incorrectly: I have never seen a NMI anyway).
