Kernel Bug Sometimes When Capturing Metadata

I sometimes see the below Kernel log after restarting depth streaming capture while capturing metadata. It happens on both JP4.6.1 and JP5.0.2. I used v4l2-ctl to test using these commands.

Enable metadata catpture v4l2-ctl -d /dev/video1 --stream-mmap
Enable depth stream capture: v4l2-ctl -d /dev/video0 --set-fmt-video=width=1280,height=720,pixelformat=UYVY --stream-mmap

Kernel error log after some depth capture restarts
