--- Comment #14 from Torsten Krah krah.tm@gmail.com --- So that is REALLY the trick. After booting to windows (vista 32bit, latest stable Ati Radeon driver), its green again when booting to 3.10.5. I don't even know now what i have done that it did work a few minutes ago with the same kernel.
So now the question is - what should i do now? Still bisecting?
