It may not be broken; it may just be misunderstood or incorrect approach.

You'll need to explain why and where exactly you think it is broken.

I am solving Stokes. I will push the example for you to run tonight. Basically, I put in a constant for the pressure as the nullspace. If you run with gmres/left it gives back a pressure with integral 0. If you run with gmres/right, it gives back a pressure with a big integral. Matt
