AdS5 type IIb supergravity compactifications on five-dimensional Einstein manifolds \cal V5 realize holographic duals to four-dimensional conformal field theories. Black holes in such geometries are dual to thermal states in these CFTs. When black holes become sufficiently small in (global) AdS5, they are expected to suffer Gregory-Laflamme instability with respect to localization on \cal V5. Previously, the instability was demonstrated for gravitational dual of \cal N=4 SYM, where \cal V5=S5. We extend stability analysis to arbitrary \cal V5. We point out that the quasinormal mode equation governing the instabilities is universal. The precise onset of the instability is \cal V5-sensitive, as it is governed by the lowest non-vanishing eigenvalue λmin of its Laplacian.
