"Stalls are a pitch problem, not a power problem."
Stalls are an AoA problem, period.
For me, as a non-pilot who once knew a bit about making stuff that flies, the single most scary thing from all the 447 and other stall threads has been the number of apparent pilots who don't seem to know this. That and the realisation that many of them don't even have an AoA indicator in the cockpit (which is probably connected to previous point).
[Actually, for several years I might have said that stall is a boundary layer separation problem, it just happens at a particular AoA - but that depends on your point of view. By the time the pilot is in control, the engineering is done, and AoA is the difference between flying and falling. ]
