Terry, Consider the possiblity of the rib buzzing you describe being due to the INTERIOR of the rib having come loose against the board while both edges still appear attached. If you can push the rib up against the board and no other obvious candidates are immediately apparent, then I would seriously consider this. You might be able to acquire some clues as to this by carefully mapping through the buzzing area with pressure and attempting to discover a pattern. These do exist even though that are, in my experience, very uncommon. I spent considerable peace of mind, money and general life attitude trying to discover the origin of what turned out to be just such a buzz, on a vertical which was a most exasperating experience. If I remember right, I eventually concluded, due to the fact that I could push on the rib and stop the buzz in certain places and not in others, that it was a hidden separation. I then forced a knife with some effort, into the joint and found such was the case. I have seen what I thought was one or two other of these over the years but did not verify such by the repair.
