chkprimit : ERROR -
According to the symmetry finder, the unit cell is
NOT primitive. The multiplicity is 3 .
The use of non-primitive unit cells is allowed
only when the input variable chkprim is 0.
Action : either change your unit cell (rprim or angdeg),
or set chkprim to 0.

Try brvltt -1 and let abinit find the primitive cell (I think you've input the conventional, hexagonal cell).
