Power unit: Watchdog timer

What does A30810 mean?

During the booting process, it was detected that the cause of the previous system reset was an SAC (System Access Controller) watchdog timer overflow. This means a critical software process failed to acknowledge the watchdog timer within its allotted time, leading to an unexpected system reset. Repeated occurrences can indicate software instability or resource contention.
