the irradiance cache method has difficulty in correctly resolving the extreme brightness values in the HDRI image. you can try the sky sampler (which, like the indirect illumination method, uses a special sampling that deals with HDRI) or tweak the HDRI (blurring it for instance) so the irradiance cache 'sees' smoother lighting.

cheers, simon w.
