Hi Daniel,

$ git log --oneline v3.6.0-rc2-next20120821-1-iniza-generic..drm-intel-fixes
1ee9ae3 drm/i915: use hsw rps tuning values everywhere on gen6+
f1a2f5b drm/i915: fall back to bit-banging if GMBUS fails in CRT EDID reads
4eab813 drm/i915: extract connector update from intel_ddc_get_modes() for reuse
a843af1 drm/i915: fix hsw uncached pte
b6c7488 drm/i915/contexts: fix list corruption
38ab8a2 drm/i915: fix EDID memory leak in SDVO

Looks like "1ee9ae3 drm/i915: use hsw rps tuning values everywhere on
gen6+" has PM fixes for i915.

I tried with only that patch on top of today's linux-next - and I can
suspend/resume again!

$ git log --oneline
v3.6.0-rc2-next20120821-1-iniza-generic..drm-intel-fixes-1ee9ae3
88eb888 drm/i915: use hsw rps tuning values everywhere on gen6+

Hope this helps others - sorry for bothering other maintainers.
