Comment 45 for bug 747205

I've reviewed the aforementioned bug reports. It is striking they have such similar symptoms and are mostly Arrandale/x86_64 specific, but there are subtle differences in symptoms so I'm unsure they're all duplicates.

There are a variety of Arrandale (aka Ironlake) kernel patches proposed upstream at http://lists.freedesktop.org/archives/intel-gfx/2011-April/010071.html.

Some of those patches are experimental bits, others are merely shuffling code around for refactoring, so it's difficult to spot the actual fixes we should care about.

In any case, I think the next action for this bug report is that we need people to test this intel-drm-next-proposed branch and tell us whether it fixes the issue; if so then the actual fixes can be git-bisected, or if not we should forward the bugs upstream.
