Symptom

A fabric switch may experience a kernel panic due to NVRAM corruption. Preceding this event, DIAG GOLD tests may report the `The RTC battery voltage is low` followed by `Bad blocks found on NVRAM`.

Workaround

If after reloading the switch is still reporting `The RTC battery voltage is low` and `Bad blocks found on NVRAM` faults, cold-reboot is suggested. Otherwise, please contact TAC team for further investigation.
