Hi @JerryChang
v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=1 --stream-mmap --stream-count=1 --stream-to=test.raw --set-fmt-video=width=1920,height=1080,pixelformat=UYVY
“bypass_mode=1” will cause kernel crash and if “bypass_mode=0” no kernel crash.

I also got the same problem V4L2 timeout leads to NULL pointer dereference in kernel in jetpack 4.6 - Jetson & Embedded Systems / Jetson Xavier NX - NVIDIA Developer Forums
nvidia@agx-dev-1:~$ cat /etc/nv_tegra_release
