Xavier AGX kernel panic after mmap

[nazaraa]

Hello.

We have devices based on AGX Xavier (Jetpack 4.3, L4T 32.3.1)
We found a way to crash the system by means of mmap.
Memory is mapped successfully, but system is crashed after memory access.
Here is mmap_crash.c (644 Bytes) to reproduce the issue. Here is log mmap_crash.log (28.9 KB)

Have you managed to reproduce this issue?
mmap returns no errors, but system is crashed after memory access.
Do you have any solutions?

Just try the mmap_crash on J4.4(r32.4.3) on Xavier without problem.
Could you check J4.4 to confirm it.
