[poky] Poky, EMGD/PVR and es2greas_x11 problem

[Keskinarkaus, Teemu]

Hi

I think this problem applies other than es2grears_x11 as well, but that's what I've used to test.

We have Atom based hw and we have made our own layer to poky that uses emenlow as a base.

Everything seems to be working fine except when I start running the es2grears_x11 it starts okay, but the movement is really jerky. The reason can be found from dmesg that is flooded with this kind of messages:

Has anyone else encountered the same problem and found out what was the problem? I found some mention this problem from google, but didn't find anything that would solve this.

I updated system to run kernel 3.10.11 and EMGD 1.18, but that didn't make any change to this problem.
