KSP_DIVERGED_PCSETUP_FAILED
It was not possible to build the requested preconditioner. This is usually due to a  zero pivot in a factorization. It can also result from a failure in a subpreconditioner inside a nested preconditioner such as PCFIELDSPLIT. 
Notes: Run with -ksp_error_if_not_converged to stop the program when the error is detected and print an error message with details.
