What if, on a long space journey, you never woke up? The computers controlling the mixture forgot to turn that hydrogen sulfide off. Eventually, it returns to normal, but you're floating somewhere near Alpha Centari...

Simple, have the hibernation unit's hydrogen sulfide tank be manually changed. Each tank only holds enough for one leg of the trip. So even if the computer forgets to turn it off, the tank would simply run out and they astronaunts would wake up. For the trip home simply change the tank and be ready to go. It'd run once again, shortly before reaching earth.
