Please excuse the spam - but perhaps this could be useful for others as well:
I wrote before that I wanted to read a previous solution as a starting point for further calculations, and that after
successful load of previous solution using ReadSolution, initial guess was always set back to zero.
Just found out it was the gmres solver from petsc I used which caused the problem:
Just adding the switch -ksp_initial_guess_nonzero made everything work fine.
