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

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 ?

b310_boot_jp502.log (57.1 KB)
b310_jp51.log (58.6 KB)

please apply this to the kernel driver to bypass this issue.

It may be right for self testing.
I will apply this patch to Image , and customer also can test this issue.

thanks to your advice.
