First Fedora Kernel with broken video resume/thaw aka FFKWBVRT i.e. kernel-3.16.0-0.rc0.git10.1.fc21 comes with 'patch-3.15-git10.xz' which closely resembles "git/commit/drivers/gpu/drm/nouveau?id=7a014a". Simple as that. Why are you asking me that bisect formality, man is it not enough that I tested two dozen kernels. poma
