Description:

Linux 3.18 seems to break GPU acceleration on my Atom netbook (945GSE chipset). The following lines in Xorg.log.0 appear to be relevant:

[ 16.088] (WW) intel(0): Failed to submit rendering commands, trying again with outputs disabled.
[ 16.371] (EE) intel(0): Failed to submit rendering commands, disabling acceleration.

This has been reported on the forums by two other people [1].

I tested the following upstream patch and it fixes the issue for me (found it via [2], patch also attached):

The issue still exists in linux 3.18.2-1; please consider applying the patch before moving Linux 3.18 to [core].
