[nsp] Cisco Router Rebooting

[Tony Li]

I concur.  The PCI parity error suggests that there's some hardware
difficulty.  It might be worthwhile reseating things just to kill
any gremlins and then isolating the problem by selective removal.

The fatality that you're seeing is that the device driver is trying
to call printf() while handling the interrupt associated with the
error.  This is a no-no because printf() blocks the process and you
can't do that at interrupt level.  You've got no process to block.
This is a pretty clear indication that this error handling code was
never tested.
