I raised this concern before.
Actually we could see dependency on issue:
https://bugs.launchpad.net/bugs/906210

for detailed analysis we had used some sensor apks.

We could see continuous traces like below while debugging:

> 01-01 21:07:57.108 W/SurfaceFlinger( 1544): ANDROID_WAIT_FOR_FB_SLEEP
> failed (Bad file number)
> 01-01 21:07:57.108 W/SurfaceFlinger( 1544): ANDROID_WAIT_FOR_FB_SLEEP

This is an Android thing and has been present since 3.1 or 3.2. It is caused by missing wakelock early suspend support, something that is not present in 3.3.

906210 issue need to solved for detailed analysis.

Lets target this for 12.05 release.

"https://bugs.launchpad.net/linaro-android/+bug/906210" is getting released in 12.04 release.
Keeping status as new as this will have to be tested and verified and then debugged in 12.04 release.

" https://bugs.launchpad.net/linaro-landing-team-arm/+bug/906210" is resolved for 12.04 release.

Tested on intermediate 12.04 build - https://android-build.linaro.org/builds/~mathieu.poirier/linaro-android-4.0.3-snowball-mm/#build=16.

I can clearly see improvement as no corruption observed while changing from landscape to portrait mode. I tried in Android app idle screen.

Do I understand this correctly that the bug will be solved by another fix? If tat is the case then this one could be moved into status Won't fix?

[Sunil Kamath (sunil-kamath)]

Yes, its its the same solution. Problem is solved with previously mentioned patch. Hence we can make it as fix committed.
