[Anmar Oueja (anmar)]

Currently, we are working on moving additional Android patches into the IglooKernel. After flushing these changes, we are review this bug in future cycle.

[Botao (botao-sun)]

Hi Anmar, have those additional patches been applied to the IglooKernel?

[Anmar Oueja (anmar)]

Unfortunately they haven't yet. I suggest we target this bug at
2012.03 as I doubt we will get the patches in Feb.

[Zach Pfeffer (pfefferz)]

Shifting to 12.03.

[Mathieu Poirier (mathieu.poirier-deactivatedaccount)]

The patches Anmar is referring to in comment #3 should come in as part of kernel 3.3, which is targeted for 12.03.

[Patrik Klinger (patrik-klinger)]

+anmar, what is the current status of this bug? What is blocking and what is left to do?

[Anmar Oueja (anmar)]

Mathieu: Can you please test this issue against the latest 3.3 kernel

[Thomas Espersson (espersson)]

Naveen: can you please test this and see if the bug is present on IK 3.3.

If so, is this related/identical to this bug:
#949367 android: kernel 3.3 doesn't come out of hibernation

[NaveenKumar Gaddipati (naveen-gaddipati)]

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

It is able to wake from resume.

[NaveenKumar Gaddipati (naveen-gaddipati)]

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

[Anmar Oueja (anmar)]

Naveen: Can you please open another bug to capture the proper fix requirement.

[Anmar Oueja (anmar)]

This fix is breaking HDMI on ubuntu.

[NaveenKumar Gaddipati (naveen-gaddipati)]

The patch was given for avoid the suspend in alpha release.This workaround will not allow the system into suspend.

[NaveenKumar Gaddipati (naveen-gaddipati)]

 debian:Remove platform suspend flag
 mach_ux500:Removed suspend flag
The above two patches will not allow the system to go to suspend.
