  Let $G$ be the Weil restriction of a general linear group. By extending the
method of semi-modules developed by de Jong, Oort, Viehmann and Hamacher, we
obtain a stratification of the affine Deligne-Lusztig varieties for $G$ (in the
affine Grassmannian) attached to a minuscule coweight and a basic element. As
an application, we verify a conjecture by Chen and Zhu on irreducible
components of affine Deligne-Lusztig varieties for $G$.
