NMI functionality
An NMI crash dump creates a crash dump log before resetting a system which is not responding.
Crash dump log analysis is an essential part of diagnosing reliability problems, such as failures of operating systems, device
drivers, and applications. Many crashes freeze a system, and the only available action for administrators is to restart the
system. Resetting the system erases any information which could support problem analysis, but the NMI feature preserves that
information by performing a memory dump before a system reset.
