Adb hang observed in Hikey 960 board

Hi there,

I’m using hikey 960 board for development activities. I have downloaded android source tree using repo init and repo sync. My branch head is at commit id bae95f19a8c1c86e59a70b40e2c0827f08c790a9. And I have downloaded hikey linaro kernel 4.9 from git using git checkout -b android-hikey-linaro-4.9 origin/android-hikey-linaro-4.9. After successfully building the images and flashing it to the board, if I try to run adb commands (especially adb root/remount command) the board gets hang or powers-off automatically. I have been stuck with this for quite long. Any support will be greatly appreciated.

I think this is related with a known bug:

AFAIK, the best choice is to upgrade to use kernel 4.19.
