A kernel panic occurs sometimes when closing camera

[261136636]

Hi, nvidia teams:
When we do not connet camera module to orin and use the following command:
*gst-launch-1.0 *
*nvv4l2camerasrc device=/dev/video0 ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1’ ! nvvidconv ! ‘video/x-raw(memory:NVMM), width=(int)960, height=(int)540, format=(string)NV12’ ! nv3dsink window-x=0 window-y=0 *
*nvv4l2camerasrc device=/dev/video2 ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1’ ! nvvidconv ! ‘video/x-raw(memory:NVMM), width=(int)960, height=(int)540, format=(string)NV12’ ! nv3dsink window-x=960 window-y=0 *
*nvv4l2camerasrc device=/dev/video4 ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1’ ! nvvidconv ! ‘video/x-raw(memory:NVMM), width=(int)960, height=(int)540, format=(string)NV12’ ! nv3dsink window-x=0 window-y=540 *
*nvv4l2camerasrc device=/dev/video6 ! ‘video/x-raw(memory:NVMM), width=(int)1920, height=(int)1080, framerate=(fraction)30/1’ ! nvvidconv ! ‘video/x-raw(memory:NVMM), width=(int)960, height=(int)540, format=(string)NV12’ ! nv3dsink window-x=960 window-y=540 \ "
to open 4 cameras, after execute this command, there we be 4 windows in the screen,
but when I use mouse to close these windows, there will be a kernel panic sometimes, the log is in the attachment.
so have you seen this bug before? how to solve it?

When we do not connet camera module to orin and use the following command:

is there /dev/video* nodes? may I know what’s the real use-case to enable the stream without camera device connected physically?
