Hello, I've been attempting to get a Shark Bay / Haswell platform up & running, and have been having some difficulties that I'm hoping you all can possibly help with. I first tried the 3.5 kernel, and had some success after applying the following patch: https://patchwork.kernel.org/patch/1229541/ This seemed to be necessary to get the 0x0c26 PCI id to be loaded by i915, and use KMS. After doing this, I had some success, but things still would become unstable, and flash test patterns on the screen about every third boot. I figured that I would move on to the tip, and see if that fixed anything. However, at the tip, I cannot get i915 to display graphics at all - even with applying the patch above. I understand that this is still under development - but this seems like a regression from 3.5 Is there a codebase that I should be using for this testing? Ben
