This setting is Enabled by default. When an NMI is issued by a critical event
the BMC performs the system to reset for recovering the system. The BMC
logs the reboot and additional error events in the SEL.
Reboot on SPINT
When any unrecoverable error condition occurs, the service processor
interrupt (SPINT) routine catches chipset register information of the machine
check (MCK) error registers and stores it in the BMC NVRAM. Each main
component of the IBM eX4 is embedded by a different machine check error
register that monitors the system operability and holds the state of that
condition.
This information is cleared after the system is recovered by a reboot. However
the BMC starts the SPINT routine to store the information in its NVRAM area.
This information is available, until the next MCK occurs.
An MCK is reported in the BMC and is caused by a fatal situation that cannot
be handled by the chipset. Typically, an MCK is issued by an essential
component of the IBM eXA4 chipset, particular components such as a DIMM,
processor, or I/O linked devices.
Note: We recommend reporting a machine check error to IBM Technical
Support, if the information is not sufficient in the System x3850 M2 and
x3950 M2 Problem Determination and Service Guide.
Ring Dump after SPINT
This setting is Disabled by default. By enabling the setting, the BMC catches
Ring Dump information from the chipset, after an MCK occurred, to log
unexpected error conditions. IBM Technical Support might request you to
enable this setting.
