I finally got rid of it. It looks that at the end it was all due to transparent_hugepages values. I disabled them and cpu spikes disappeared. I am sorry cause it's something I usually disable on postgresql servers, but I forgot to do so on this one and never thought about it. Thanks a lot for all your helpful messages!
