Posting on behalf of the customer.
We are performing certification testing with UL, during testing device suddenly stop working.
We check all the voltages, it was fine. After that We enabled the Linux Kernel Low level log in the Linux kernel configuration. After enabling this, we got the below kernel panic error. I think, this error is internal to the Processor bus.
