Kernel panic has occurred when doing reboot stress test with jp5.0.2

[samwise.yang]

It may happen while boot at our custom xavier NX board, the probability is about 1/20.

I have some tries below:
1、It can repeat steadily with jp5.0.2;
2、I have check some historical topic, the boot failure is similar, but can’t find correct workaround;
3、It can also happen when the device system update to jp5.1;

Is there some methods to solve this boot panic with jp5.0.2 ?

It may be right for self testing.
