ADB hang issue is observed in latest kernel 4.9 version


Randomly ADB hang issue is observed,and unable to collect logs in that moment as i don’t have serial console setup.
depending on adb to collect logs.
Anybody have idea about this ADB hang issue .


@leo-yan and @guodong any idea on this ADB hang issue.


Seems like this is a hang issue. So this is real hang like mouse also doesn’t work?

Anyway, there have two possible issues may introduce hang: the first possibility is related with scheduler bug with WALT, could you try the patch in the mailing list:

Another issue related with CPU power supply, could you try to update the latest booting image in the folder:; you could see Guodong upgraded the booting images one day ago for fixing CPU power supply issue.
