    What do you see on the screen? Does it look like a Mac OS X kernel panic with translucent text on the screen?

    An NMI here is most likely used to implement a watchdog timer, to make sure that other interrupts are being handled in time.

    Or... you might've accidentally found a secret Apple-designed press to deliberately cause one for debugging. As in:

    A kernel panic is a crash of the whole OS as opposed to just a single app crashing. Under Mac OS X this is fairly rare and this the first time I've seen it documented for iOS. This is something that hopefully never happens to you, but if it does you turn off the device and turn it back on and in most cases you should be fine.
