I'll try updating again tomorrow before I report anything.
That sort of inconsistency leads one to suspect a hardware issue. Perhaps a fan that's not running so things are too hot, a power supply that's dying, dirty memory connectors, etc.
I ran memtest for over 30 hours (13 full passes) and got 0 errors. I then updated to kernel 4.1.3 and after an hour or so got the freeze again. Going back to 4.0.7 fixes it.
I'd file a BZ but for some reason I can't see the latest freeze in journalctl (the earlier ones are all there). The journal timestamp for the "-xb -1" listing is a couple of days ago when it should be today.
