iMX6/Android: hang after "adb root"

Hello community !


We're facing an issue with imx6 Android KK-4.4.2 BSP and kernel 3.0.35. Indeed when I  use "adb root" any subsquent adb command hangs.


For instance, with the following sequence :

$ adb root

$ adb shell

The shell command hangs


But if  I use adb kill-server or I un-plug/plug the USB cable between the two commands it works. I read the following post adb hang issue with i.MX6DQ kk4.4.2-1.0.0-ga. which seems to be a similar issue. They talk about a patch that can be apply on kernel 3.0.35 but I can't found the patch in the discussion.


We won't be able to update the BSP for now, is there anything we can do to fix this issue ?


Best regards,

Damien Dejean.
