[perf] System S4 hibernate resume time is longer than required

[Zhao Fan]

Bug detailed description:
--------------------------
Image: Created on 12/19/2007
This bug is to track system S4 resume performance issue. The requirement defines that "Time from user pressing wake-up button to desktop UI being fully responsive <= 10 sec ", right now we need 30sec. We also record the detail resume time in different stages:
BIOS: 18s
load image: 7s
left resume time: 5s.

Reproduce steps:
----------------
1. ume-hibernate to S4 suspend the system
2. push power button to resume the system, and record time

Current result:
----------------
The S4 hibernate resume time is longer than required

Expected result:
----------------
1. S4 hibernate resume time should be less than 10s per defined.

Basic root-causing log:

QA: You need to assume BIOS will reduce their time down to 5 seconds. The goal should be for S4 to resume in 5 seconds.

Rob, thanks for clarification. Yes, I assumed so, and that's why this bug is still open :)

Fan:
how about set the bug as medium?
we just use it to track the gap, I do not think it should be the high bug.

It is very difficult for us to use only 5 seconds to resume from S4. Currently we need 8-9s at least to resume.

Will not fix it for moblin1.0
