Check the System Event Log (SEL) or crash dumps from Operating Sysstem to identify the source that triggered the watchdog timer reset. Update the firmware or driver for the identified device. iDRAC has warning event: "The watchdog timer reset the system". This patch fixes this issue by adding the reboot notifier.
