Auto suspending and console unresponsive -Android6.0.1 on iMX6QP

Hi

As I have mentioned Im running Android 6.0.1 with 4.1.15 kernel on iMX6QP Sabre.

I am not sure if this is normal but the system keeps suspending automatically when I try to work on the console and it is unresponsive until I hit the power button. It keeps suspending within few seconds so much that I cant even enter a command on the shell terminal. Also it had suggested to enable no_console_suspend so I entered that in the bootargs in uboot terminal. But still it keeps suspending. Here is the serial debug output.

Hi,

For this case you will have to debug and check the suspend issue, also have to take a look a your device tree power management configuration:
