  We prove that the Hodge-de Rham spectral sequence for smooth proper tame
Artin stacks in characteristic p (as defined by Abramovich, Olsson, and
Vistoli) which lift mod p^2 degenerates. We push the result to the coarse
spaces of such stacks, thereby obtaining a degeneracy result for schemes which
are etale locally the quotient of a smooth scheme by a finite linearly
reductive group scheme.
