Summary This paper deals with possible modal degeneracies between spatial Orr-Sommerfeld model in plane Poiseuille and boundary-layer type mean flows. In analogy to the Benney-Gustavsson resonance mechanism exact modal coalescences can be observed for three-dimensional disturbances. At these direct resonances linear theory implies a locally algebraic growth and the corresponding potentially, large amplitudes may initiate the nonlinear state.
