I tend to hibernate most of the times, never had a problem. Suddenly I kept getting "Your PC needs to be repaired" coming out of hibernation consistently. Regular booting, no problem. Out of curiosity I checked to see if some update had been applied that might have caused this behavior. What I found was that failed KB3087040 update.
After manually applying the update and back on "Your PC is up to date" status, hibernation started working again.
