Baky (cc'ed) is getting a strange error on Cori/KNL at NERSC. Using maint
it runs fine with -with-openmp=0, it runs fine with -with-openmp=1 and
gamg, but with hypre and -with-openmp=1, even running with flat MPI, the
solver seems flatline (see attached and notice that the residual starts to
creep after a few time steps).

Maybe you can suggest a hypre test that I can run?
