Kernel NMI Watchdog: CPU Soft Lockup - Troubleshooting Guide

This is a kernel message indicating that the NMI (Non-Maskable Interrupt) watchdog detected a soft lockup on CPU#1. A soft lockup occurs when a CPU is stuck in a loop or is unable to handle interrupts for an extended period of time.

In this case, CPU#1 has been stuck for 23 seconds, which is a significant amount of time. This can cause system performance issues or even system freezes if not resolved.

The kernel message suggests that there is a bug causing the soft lockup. It is important to investigate and fix the underlying issue to prevent further occurrences. This may involve analyzing the system logs, checking for any recent changes or updates, and debugging the code that runs on CPU#1.

Soft lockups can be caused by various factors such as driver issues, hardware problems, or software bugs. Identifying and resolving the root cause of the soft lockup is necessary to restore normal system operation.
