Xavier AGX kernel panic after mmap

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)
