IMX8MN HDMI-IN memory corruption

Hi,

We are experiencing issues that look like memory corruption (eg. random processes crashing due to SIGILL, "corrupted double-linked list" messages from glibc, etc.) whenever gstreamer which is using HDMI-IN is stopped and restarted. (Only stop/restart is problematic, gstreamer is fully working otherwise.)

We are able to reproduce it in about 15 minutes with the following script:

while [ 1 ] ; do
gst-launch-1.0 -e v4l2src device=/dev/video0 ! waylandsink window-width=751 window-height=422 &
sleep 15
GST_PID=$(ps auxw | grep 'gst-launch' | grep -v grep | awk ' { print $1 } ')
[ ! -z $GST_PID ] && kill $GST_PID
sleep 15
done

For the kernel are using commit 95448dd0dc9b621ae027cbefedaaa7c3d0d3ad2d from linux-imx 5.15 branch.

Hello,

Yes, that error is due to a memory consumption, are you using the gpu beside the gstreamer and vpu?. please check your memory.

Regards
