Boy, can I relate to this problem! I currently have two lenses and my camera at Canon Repair because I was having problems with achieving sharp focus with the 135L and I had all I could take with trying to micro-adjust it.Right before this I returned a Sigma 85mm for another copy do to the same problem. I wasn't sure if the problem was the camera or the lens, so off they went. It's the first time I have ever sent anything to Canon and hopefully I will have them back next week. Here's the link I started regarding my experience ...

Your lens is clearly front-focusing. It also looks like focus is pretty sharp with this copy, it's just not focusing where you want it to so if I were you, I'd send the camera and the lens off to Canon.

Good Luck! Let us know what you decide to do and how it turns out!
