15. Linux* Kernel Panic Records
The OpenIPMI 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.
