Unable to handle kernel access to user memory

[omni-www]

When I want to use copy_to_user(app_addr,kernel_addr,data_length),the kernel panic.

I had add it to deconfig,but no function.
the code it’s worked on my old version jetson Linux.it’s no problem.

.It’s my kernel panic log:

Hi,
It seems like the address is invalid from the log. For further check, would need other users to share experience.

Jetpack 5 is K5.10 and Jetpack 6 is K5.15. If you would like to try, may try Jetpack 6.1 and see if it works.
