I am encountering a rare issue on my Xavier device running JetPack 4.6.4. Occasionally, during startup, the nvpmodel service triggers a kernel panic, but restarting the device usually resolves the issue. Here are the details:

What could be causing this issue? Could it be related to the nvpmodel configuration or hardware? Are there any preventive measures or further diagnostic steps I can take?
