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?
Dave.
Arg. It's been ok on my ILK systems, but Chris has found some issues with out watermarking code iirc; apparently we're underflowing the display FIFO, causing all sorts of trouble. If it works before the pull of Dave's tree, can you bisect?
I think he'd fixed them in the tree I pulled locally to test, I'm guessing this might be that we are running the Fedora userspace driver and you guys are all on master or something, which would mean some ABI guarantee got busted.
I'm going to try a local test upgrade to 2.14.0 just to see.
Dave.
