[Bug 902049] Re: Panda : Warning messages coming from " drivers/video/omap2/dss/dss.c"

 

There's no point using our 3.1-based kernel for Android any more.

You should test with tilt-android-tracking kernel, currently based on
3.2-rc7.

This kernel has support for accelerated graphics on ICS.

I did a lot of work on suspend over the last couple of days, on our
android tracking kernel, you shouldn't see these warnings any more and
suspend on ICS is working fine.
