这个怎么排查啊，偶现的

orin nx 16G ， jetpack5.1.4

我们的设备在客户现场，没办法接调试串口

4

Could this issue be reproduced with specific steps?
Happen rate?

5

偶现的，没有复现步骤。我也不太清楚怎么能复现问题。有没有什么调试手段，在出现问题的时候能看到相应日志。 或者打开内核的什么log调试？

6

/sys/fs/pstore/

Is there any console-ramoops-0 node in above path?

If there is, check it right after your issue is reproduced.

7

内核有什么开关打开可以增加一些调试信息的输出吗？
