  We prove a Freidlin-Wentzell result for stochastic differential equations in
infinite-dimensional Hilbert spaces perturbed by a cylindrical Wiener process.
We do not assume the drift to be Lipschitz continuous, but only continuous with
at most linear growth. Our result applies, in particular, to a large class of
nonlinear fractional diffusion equations perturbed by a space-time white noise.
