Lowlights: it's broken.
I get millions of messages like:

and everything is very choppy. I assume it's the power saving thing that broke again, but that's just a total random guess, I have nothing to actually back that up with.
It worked fine after boot, but those problems began at 8287.139375 (about two hours after boot - it may have coincided with screen saver, but who knows?) and have been happening constantly since. The machine is not really usable, I'm writing this with annoying 2-second pauses every once in a while.
Okay I'll try and reproduce and curse Chris and Jesse, does booting with i915.powersave=0 help any?
I've also noticed Chris has some more patches in drm-intel-next I haven't got in this pull request.
I don't think he's sent me a pull request though so not telling how stable they are.
Dave.
