No, it is related to the phase of the moon. When the moon is
in the seventh house and Jupiter aligns with Mars, the Fermi
energy will be correct.

Seriously: I can't stand any longer this attitude of blaming
pseudopotentials for everything. Anyway: it is related to the
way Fermi energy is calculated and to the peculiar form of the
Fermi surface in graphene.
