  We derive equations of motion for dissipative spin hydrodynamics from kinetic
theory up to first order in a gradient expansion. Choosing a specific form of
the matching conditions, relating the change in the spin potential to the spin
diffusion and spin energy, we then show that the equations of motion,
linearized around homogeneous global equilibrium, are causal and stable in any
Lorentz frame, if certain sufficient conditions on the transport coefficients
are fulfilled.
