  We consider massive type IIA compactifications down to 4 dimensions in
presence of O6 planes and D6 branes parallel to them, in order to preserve
half-maximal supersymmetry in 4D. The dynamics of open strings living on the
spacetime filling branes is taken into account, in the gauged supergravity
description, by adding extra vector multiplets and embedding tensor components.
The scalar potential gets new terms that can be matched with contributions
coming from dimensional reduction of the non-Abelian DBI and WZ brane actions.
In this setting, we analyze the vacuum structure of the theory and find novel
AdS$_4$ vacua, both supersymmetric and non-supersymmetric ones. Furthermore, we
address their perturbative stability by computing their mass spectra. Some of
the vacua are found to be perturbatively stable, despite their being
non-supersymmetric. We conclude by discussing the reliability of our setup in
terms of higher-derivative corrections.
