These are appearing throughout the day while the system is not being used.
The OS was built from SDK Manager using JetPack 5.1.2 on Jetson Orin Dev board, L4T 35.4.1
What is causing these messages and how do you fix the issue ?

Thank you

Sorry for the late response.
Is this still an issue to support? Any result can be shared?

Hello @kayccc - any updates ?

I was checking this issue today and see things have become worse!

Is there a way to force a fsck on the boot SD Card on reboot ?

Hi,
Please upgrade to Jetpack 5.1.3 and try. See if the issue is present in latest release.

If the issue exists on 5.1.3, please share the method to replicate it on Orin Nano developer kit. We will set up and try.

We have started testing on Jetpack 6.0 DP. Seeing similar messages :

Hi,
Please share the steps so that we can set up and try.

I boot the Orin and leave it running. I have a console window that shows those messages. I’m not even logged in to the system - so the system is idle.

Hi,
Please try 6.0GA(r36.3).
