Thanks to this bugreport [1] now suspend and resume work as expected on Fedora 21, finally! Issue was with missing TPM modules! One solution would be to disable TPM in EFI/BIOS and other to install missing kernel-modules-extra package. Now resume finally works! Also suspend now takes almost twice as long, and screen blinks quite few more times like this: on-pressed_suspend-off-on-off-on-off But main thing is that both suspend and resume work now as expected.
