}However, I’m still encountering this issue (in all streams). Has anyone else experienced this, or does anyone have additional suggestions for troubleshooting? Any help would be appreciated!

Using a Jetson Xavier AGX devkit with JetPack version 5.1.2 I'm encountering an issue when I enable RGB stream capture using the following command:
v4l2-ctl -d /dev/video2 --stream-mmapThis problem occurs with multiple devices intermediately after running the last command, specifically /dev/video2 (RGB Stream), /dev/video4 (IR Stream), and /dev/video5 (IMU Stream). The capture itself seems to work without any issues, but the kernel log contains the following error messages:
Additionally, the /dev/video0 (Depth Stream) produces the following kernel log:
Has anyone else experienced this issue or have any insights on how to resolve it? Any help would be greatly appreciated!
