I have tracked it down to SuperLU_dist, which was few months ago picked
as new default by Garth. It works fine with MUMPS. Still, it would be
good to know if it is faulty install on my side or bug/numerical problem
in solver. So, can anyone try?

Running
$ mpirun -n 2 python demo_mixed-poisson.py
on PETSc produces obviously wrong results. Adding line
print norm(w)
results in 1.3060017846e+11 instead of correct 0.611356580181. Strange
is that with
parameters['linear_algebra_backend'] = 'Epetra'
it gives me correct results. So is it my installation or are DOLFIN
PETSc wrappers broken?

I get correct norm with PETSc and about a week old version of master.
