Overview the K_POINTS in input file, I don't see any problem in it. But I
have 2 wondering points:
  1. Have you run scf for your system yet? If yes, you can find Fermi
energy level for the metal system.
  2. You are consider ibrav =0, why you put  cosAB, cosAC or cosBC

So, the solution is run with "scf"  first, then run with "bands", More
detail let see in example01.

Good luck,

Linh
