15. Linux* Kernel Panic Records
The Open IPMI driver supports the ability to put semi-custom and custom events in the system event log if a panic occurs. If you
enable the “Generate a panic event to all BMCs on a panic” option, you will get one event on a panic in a standard IPMI event format.
If you enable the “Generate OEM events containing the panic string” option, you will also get a set of OEM events holding the panic
string.
