First off, I think the idea of this thread isn't great. Problems/Solutions will get lost, and its harder for someone to search for something that comes up. I'd say a megathread for this isn't a great idea.
But anyways, just cut a small hole in the roof and look up there. Either way you'll probably need to do something in that area, so why not make a hole if there will be one anyway. An access hatch is probably a good idea.
One solution might be to insulate the area, and I've seen good success with spray foam insulation. It will also depend on your construction and whether this will be able to insulate the pipes in the cavity (ie is the attic space warm or cold (not temp wise, construction wise).

I've inspected the fixture, it seems fine. I've inspected the switch, it seems fine too. It's on the same circuit as a GFCI outdoor outlet. If the outlet is tripped, the light is off. The outlet works just fine all the time....
Ideas?

Sure that it isn't a motion sensing light? They generally only work during dark times, and then also have manual modes which are enabled by series' of switch flicks. If you don't know you have one and how to use it, they can be a PITA to understand. My money is on that.
