AM3358: Android Deepsleep mode issue

Hello Champs,

Hardware: AM3358+TPS65217D

Software： TI_Android_GingerBread_2_3_4_AM335x_Sources

Question: In the deep sleep, press power key, the system is waken up, but then the system enters the sleep mode again. 

The initial reason customer guessed: The kernel was waken up and generate the "input" event, but the event can't be captured by the application level which caused to fail to get the wakeup lock and then the system re-enter the sleep mode. 

Below is the log:
