I have fixed this by setting the KSP op:
call PCFieldSplitGetSubKSP(spc,i,subksp,ierr)
call KSPSetOperators(subksp(2),solver%schur,solver%schur,ierr)
Thanks,

Mark, where is the information getting lost? If the interface does not
work correctly, we

I would set a breakpoint at PCFieldSplitSetSchurPre_FieldSplit and then
watch -l jac-schurpre since it appears that your information is being
lost somewhere.
The 'ptype that comes in to PCFieldSplitSetSchurPre_FieldSplit is
..._SCHUR_PRE_ALL (not .._USER). Could the enums be messed up in
Yep, it looks like SELFP was not added to FORTRAN:
6:04 1 edison03 master ~/petsc_private/include$ grep
PC_FIELDSPLIT_SCHUR_PRE *
petscpc.h:typedef enum
I fixed the messed up fortran enums with:
!
! PCFieldSplitSchurPreType
!
PetscEnum PC_FIELDSPLIT_SCHUR_PRE_SELF
PetscEnum PC_FIELDSPLIT_SCHUR_PRE_SELFP
PetscEnum PC_FIELDSPLIT_SCHUR_PRE_A11
PetscEnum PC_FIELDSPLIT_SCHUR_PRE_USER
PetscEnum PC_FIELDSPLIT_SCHUR_PRE_FULL
