attachment is logcat output.

From the logcat message, I found these error:

=========================
1) the build is based on the below commit:
gecko: 3916db8cb84dce2afd90c01254692c33078b8b68
gaia: 91ad7fb9dc82e87021a2bac5900f2dd91f124405

2) I tried to disable boot animation(removing /system/media/bootanimation.zip), and the error would not happen 

3) tried to disable hwcomposer, the bug is still existing

4) build from the below commit works well
gaia: a41c7921fbf0839b894f277261dad4a22507f979
gecko: b3cd9efc36ce4556117c56ae11807d839023f603

similar with Bug 821480 ?

@Cyvins In what device and branch are you seeing this?

wrt. branch, please just provide the AU number that this is seen on.

Comment 5

[cyvins]

I am using the v790 device,and both AU30,AU31 have this issue, AU27 does not have such issue, the current cdr code is AU31. thanks.

Comment 6

[cyvins]

it's v1.0.1 branch.

I'm not familiar with that device. Who's the OEM?

Comment 8

[cyvins]

I will try kis device, I think it should have such issue, and Michael should have this v790 device.

Comment 9

[Michael Vines [:m1] [:evilmachines]]

Yep we have both.  Should be able to check this here on Monday.

Comment 10

[Diego Wilson [:diego]]

I loaded the latest from the v1.0.1 branch of gecko/gaia on the v790 device. I didn't see any gralloc error.

@cyvins, what branch are you trying to test?

Comment 11

[Firefox_Mozilla]

Hi, Diego

Our build is based on the below commit of gecko/gaia, branch v1.0.1, AU31
gaia: revision="91ad7fb9dc82e87021a2bac5900f2dd91f124405"
gecko: revision="3916db8cb84dce2afd90c01254692c33078b8b68"

could tell me the commit id that you have tested?
and did you load the image built from cdr or just update the gecko/gaia? 
Thanks.

Comment 12

[Firefox_Mozilla]

do you think it is the same issue with bug 847207?

Comment 13

[Diego Wilson [:diego]]

The problem goes away when I remove /system/media/bootanimation.zip. I noticed v790 builds have a splash.img. I haven't seen that in other equivalent devices. Any chance this bootanimation.zip and splash.img are somehow clashing?

Attachment: Wait for boot animation before initializing layer manager

Comment 15

[Michael Wu [:mwu]]

Can someone try this patch and see if it fixes the issue? It works for me on the Keon, but I've had more difficulty reproducing on the open.

This patch forces us to wait for the boot animation to finish animating before touching any opengles stuff on the gecko side. Currently, we only wait for the boot animation before attempting to draw, so gecko attempts to do opengl init in parallel.

Comment 16

[Diego Wilson [:diego]]

The patch fixes my ZTE open. I say land it! :)

Comment 17

[Firefox_Mozilla]

I will try it. Many thanks.

Comment 18

[Firefox_Mozilla]

This issue can be fixed by the attached patch. Thanks.

Wait for boot animation before initializing layer manager

Andreas, do you mind reviewing this patch? I think we're a bit short on gonk widget peers.

This patch forces the boot animation thread to stop running before attempting to initialize opengl. It stops the boot animation before we attempt to create an opengl layer manager. Apparently initializing opengl while the animation is running randomly causes bad things to happen.

Does not make sense to create a regression issue.
