I'm moving my company's distro from 2.6.38 to 3.2.X (currently 3.2.2)
- and have found a regression in i915 that I'm hoping someone here
might have a fix for, already.
On some older platforms, I'm seeing the stack below that results in
the screen never showing anything.
Any thoughts, patches, suggestions are appreciated.

This patch is simply still under review and testing, so if you can, please
test it. You need the latest drm-intel-fixes branch from:
https://git.kernel.org/?p=linux/kernel/git/keithp/linux.git;a=summary
Then apply the patch you've linked to manually. If that does not help,
please file a new bug report on bugs.freedesktop.org against drm/intel.
Atm many people are already travelling to fosdem, so it could get lost.
Yours, Daniel

FWIW, I found the following patch that seems to solve the issue, on
this platform:
https://bugs.freedesktop.org/attachment.cgi?id=56178
linked from:
https://bugs.freedesktop.org/show_bug.cgi?id=42263
I was unable to find this committed in any of the dev trees, however.
Does this have any known issues on other platforms?
