No luke for me.
Updated dolfin but still the same results.

Is it suppose to have some different outputs from the  solver?
In the uBLAS interface there is an output for the factorizing step.


No. PETSc takes care of re-using the factorization, so we can't easily get output when the factorization is being performed.

I just get
'Solving linear system of size 2868 x 2868 (PETSc LU solver, umfpack)'
No factorization output anywhere.
