Reading your initial post again, are you saying there is an actual focus problem where the camera is missing or changing or that points are registering for no apparent reason but not affecting the outcome of the system or shots.
In any case, it sounds easy enough to reproduce. We just need to narrow down the variables. How many lenses can you get this to happen with?

There was an actual focus problem. The points were changing from the center focus point to all points. I was using a 17-40 f4L that was sent instead of the 24-205 f4L in my rental order. I'll play around with it today with the 17-40, my 85 f1.8 and 70-200 f2.8L II to see if it is affected by the lens.
OK, I went out and played with it more before I ship it back tomorrow. I have discovered that the focus points can be configured in landscape AND portrait orientations separately through the view finder. I turned the camera to portrait orientation and got the auto focus points lit-up. I immediately looked at the setting in the Q menu and it displays center focus point no matter which way the camera is held. So, I adjusted the focus point to the far right in the landscape orientation then held the 6D up in the portrait orientation and set the bottom focus point (far left point in landscape mode) and it worked like a charm. Two separate focus points. Then I turned it in the portrait orientation again, this time with the shutter release on the bottom and got AF focus points again! So you can set the focus points for the 3 different orientations that the 6D can be used in! Pretty cool! Not sure if I discovered something everyone here already knew about but I don't recall reading about it anywhere here or in reviews. BTW, it gives you the same focus point in landscape orientation whether the camera is held right-side-up or upside-down
