Hi,
I’m testing our custom Xavier NX board using L4TR35.3.1.
During the process of repeating the power cycle test of the board 456 times, there were 2 instances of very slow startup. Upon opening the serial port and printing logs, the following issue was discovered.
It seems the CPU get failure

What is the reason for this, is it due to hardware design or a bug in the L4T version?
