Bug Description
Description:
while in UME beta 4 testing, we found the S3 sleep is not stable. After entering S3 state, the wake-up is not stable. Sometimes, the screen turns to white, but could not recover to the orignal state when sleeping.
Reproduce Steps:
(1)use "pm-suspend --quirk-
(2)wait for the system go to S3 state
(3)press power button to wake up the system
Expected result:
system could be easy to go to S3 state and easy to recover from S3 state.
