The system receives a nonmaskable interrupt (NMI) that is generated for the BMC watchdog timer (WDT).
In this scenario, you expect the system to automatically restart. Instead, the system stops responding. Additionally, the IPMI driver does not save the stop event records on the BMC, and no memory dump file is generated.
Note The NMICrashDump registry entry is an NMI switch that specifies whether the system performs standard software error-processing when a hardware error generates an NMI. When this registry entry is set to 1, the system should perform standard software error-processing. For example, the system might display a Stop error message in this situation. Itanium-Based Systems can generate a memory dump without this registry entry. This registry entry is only needed on x86 and x64 based systems.
