I have now downgraded all of these systems to 3.19.8-031908-generic (Mainline). We'll know in a couple of days if this fixed it (or as soon as a few hours if it didn't fix it, possibly). I'll update when I know anything else; good so far! 4.0.9 definitely didn't fix it completely, but MAY have made it less frequent.
