imx8mp Android 13 HDMI hotplug resulting in kernel crash

[shiva141]

Hi 

We are using imx8mp 2gb ddr RAM  variant with  Android source imx-android-13.0.0_1.2.0

We made uboot change and CMA changes in /device/Boardconfig.mk CMA macro for  2gb variant to boot.

All functionality are working but we experience kernel panic when we disconnect HDMI from target.

when we detach HDMI board reboot with below log;please share you input for fixing this
