An infinite ferromagnetic medium with orthorombic crystal field anisotropy and with a constant dc field applied along the easy axis is considered in the framework of the Landau-Lifshitz-Gilbert equation. The linear stability analysis for the uniformly driven plane domain Wall ("Walker wall") is presented, using the method of the normal mode expansion on the basis of a suitable complete set of orthonormal functions. It is shown that the "slow-moving" walls are always unstable, while the "fast-moving" walls are stable for the uniform perturbation. For the non-uniform perturbations ("corrugating mode"), the fast-moving walls become rather unstable and the critical field Hc for the instability is a bit lower than Ho (Magyari and Thomas criterion) which corresponds to the maximum wall velocity vo. We have the relation, Hc < Ho <Hw (Walker limit field).
