I was about to give up trying to recreate this. Everything was updated as a hour or so earlier today. Meaning in the last 5 days, whatever updates were prompted had been applied as and when they showed up and I got around to doing the updates. System had not been restarted since the time below. It had been up for over 5 days now since the last time it froze.

This is the first time I have seen any logs that could be useful ...
