This seems to be Cholesky ... which would not work for you if you are not symmetric (Navier-Stokes). If GAMG works then and pilut going crazy but quite there yet, I would think there is a hypre interface problem of some sort. Hypre has been used a lot so this is a surprise. Do you use AIJ matrices? Not BAIJ or anything else.
