[Intel-gfx] v3.6 haswell regression from v3.5?

[Ben Guthro]

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?
