I noticed this problem at least some months ago (I track -stable on it when I have time/envy) and adopted the anti-Murphy attitude (wait for -RELEASE and recheck) > Would it be possible for you to dedicate some time narrowing down when > the problem was introduced? > > A good starting point might be to try 8.0-RELEASE and then 8.1-RELEASE > (just download + burn + boot livefs images and try that).
