In my 7 years of riding, I've noticed that bikes generally will handle like a plank of wood when the tires are really low on air, at least that's the only time I've experienced the handling like a plank of wood.
Also, your bike doesn't have any lowering links on it does it? That can definitely contribute to the plank of wood feeling.
One other thing, it could be time for a suspension refresh like others stated, I experienced this not too long ago with our 1st gen, it had leaky fork seals and handled terribly, after new fluid and fork seals the bike seemed to handle almost as good as bike with stock links.
