android: kernel 3.3 doesn't come out of hibernation

[Mathieu Poirier]

Board: v11(sdk)
Build: https://android-build.linaro.org/builds/~linaro-android/snowball-ics-gcc46-igloo-stable-blob/#build=192

On android the 3.3 kernel can't be taken out of hibernation by either pressing the blue botton or providing mouse input. The serial console is also unresponsive. No ouput can be captured.

[NaveenKumar Gaddipati (naveen-gaddipati)]

We are able to reporduce the issue with the latest integration kernel.

This is an woraround to fix without allowing the system togo into sleep.
We need to implement proper sudpend and resume functionality for all the drivers

[Anmar Oueja (anmar)]

Naveen: Can you please file a bug to capture the requirements of the real fix.

[NaveenKumar Gaddipati (naveen-gaddipati)]

The patch was integrated in alpha release.We are not able to reproduce the issue using the ubuntu 3.3 release with the patch given for alpha release

[Abhishek Paliwal (abhishek-paliwal)]

On Android release:
https://android-build.linaro.org/builds/~linaro-android/snowball-ics-gcc46-igloo-stable-blob-12.04-release/#build=6

I do not see device going into suspend mode.
Logs never show: "request_suspend_state" , "Freezing user space processes"
Also,
After display timeout -> display does not dims/or turns OFF.

[Anmar Oueja (anmar)]

I think we prevented suspend altogether. Sunil will know more about this.

[Sunil Kamath (sunil-kamath)]

Yes, currently Suspend/Resume is disabled. This is because some of the dependency from drivers that need to be solved.

we have issue ongoing for this:
