FWIW, I've been having similar problems with 3.5-rc7. With 3.5-rc6 my laptop resumed fine, but since updating to -rc7, it often seems to just sit there after opening the lid -- the moon/sleep LED stays on, and the power LED smoothly cycles on and off, as if it's fast asleep. Even pressing the power button doesn't have any effect (until I hold down the power button long enough to turn off). I guess I'll start a bisection, but it's slow going because it takes multiple tries to know for sure if a kernel is bad. The only commit between rc6 and rc7 that looks like it might be related is dc332fdf9f373a87b1e2f423b5b004b2a3c37e1a ("ACPI / PM: Leave Bus Master Arbitration enabled for suspend/resume"), which apparently fixes some other laptops. But perhaps I'll try reverting that and see how it goes. - R.
