I tested 4.16.3 with just your patch (+ the unrelated btrfs trimming fix 
I carry for a long time already) and it did at least 15 boots 
successfully (without hanging). So far also no "error loading smart data 
mail", but it takes a few days with suspend/hibernation + resume cycles 
in order to know for sure.

Thanks,
