//Detailed problem description goes here. This type of guru meditation repeatedly occurred and back trace result doesn’t seems to point out any application related code: Kinldy find the backtrace result below.

Expected Behavior

The device should work normally.

Actual Behavior

The device is set up to run continuously but it is observed that same type of guru meditation happened 3-5 times in whole day.

Steps to repropduce

1. Run system for 6 to 8 hours
2. At some point system resets with message Guru Meditation Error: Core 0 panic’ed(Interrupt wdt timeout on CPU0)
3. The occurrence of guru meditation is un-predictable but it is observed that if the system continuously running for over 6 to 8 hours at least one time it experienced Guru meditation reset.

// It helps if you attach a picture of your setup/wiring here.

Code to reproduce this issue

// If your code is longer than 30 lines, GIST is preferred.

Debug Logs

Debug log goes here, should contain the backtrace, as well as the reset source if it is a crash.
Please copy the plain text here for us to search the error log. Or attach the complete logs but leave the main part here if the log is *too* long.
