10.2.1 FP (NMI) Interrupt – Next Steps
The purpose of this button is for diagnosing software issues – when a critical interrupt is generated the OS typically saves a memory
dump. This allows for exact analysis of what is going on in system memory, which can be useful for software developers, or for
troubleshooting OS, software, and driver issues.
If this button was not actually pressed, you should ensure there is no physical fault with the front panel.
This event only gets logged if a user pressed the NMI button or sent an IPMI Chassis Control command requesting this action, and
although it causes the OS to crash, is not an error.
