So I now get weekly calls from someone on the TiVo Executive Response Team, yeah terrible name, to update me on the progress on fixing this issue. Or more correctly, the lack of progress. Disabling the SkipMode stops the problem, but then you cannot just press one button to skip all the commercials. TiVo disabled SkipMode on mine and it did stop the continuous rebooting. Today's update was to ask me if I had a specific episode of Stephen Colbert's show on my TiVo, an episode from mid-May. Now we do record Colbert, but that episode is long since aged off the unit. They re-enabled SkipMode on my Edge this afternoon, though it does not work so they probably did not re-enable it.
So they are working on the premise that the problem was caused by this specific Colbert episode, though I doubt they really have a clue as to what is really causing this.
