Bug Description

The parameter "use_petsc_cusp_hack" should be removed once it has been verified that it is no longer needed.

If the right-hand side of a linear system solved with the PETSc Cusp backend is not touched prior to solve, for example by calling VecNorm, then the right-hand side will be set zero when the solution is being computed (and the solution comes out wrong).

The bug has been fixed in petsc-dev.
