Here's an input which seems to work:

&END

----------------------------------------------------------------------

  Notes:
   - The k points were in the wrong section, they must be in the
      '&SYSTEM' ... '&END', not with the '&ATOMS' ... '&END'
   - One has to use a diagonalisation scheme (Lanczos in my input)
      with k points, ODIIS doesn't work
   - I switched to the automatic generation of k points, just as it
      was easier
   - The same applies for using 'SCALED' coordinates
   - I went for the 'LMAX=D' in the pseudo and to KLEINMAN-BYLANDER

    Yours,
