I'll get started on bisecting the changes between -25 and -26, and add a comment here when I have a test kernel. Just to double check - you're sure it's OK in -25? Because there are a lot of scheduler changes that were in -25, and also because there aren't that many changes between -25 and -26, and they are all graphics driver changes.
