Description (partial)

Symptom:
During a switchover, the internal reset-reason will report the last reason reload as a hardware watchdog which can be misleading. The system reset-reason will accurately report the switchover:


N7K# show system reset-reason
----- reset reason for module 1 (from Supervisor in slot 1)                                                                                          ---
