The perturbation of a uniformly decaying equilibrium is studied within the framework of resistive magnetodynamics. If the time of decay of the equilibrium state is large, the eigenmodes are the same as in nonresistive MHD. Nonresistive instabilities persist but the oscillating displacements have an increasing amplitude and an increasing period.
