imx8mp Android 13 HDMI hotplug kernel crash

shiva141 — Mon, 18 Nov 2024 06:31:45 GMT

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 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 attached log;please share you input for fixing this

Unable to handle kernel paging request at virtual address ffffff80a0bd0000
.

[ 85.937731][ T57] Memory Limit: none

and Board reboots.

Hello,

This is due to hdmi stay open in kernel no matter if you have 4GB or 2GB it will create a panic scene.
