For me - the issue is a month old, but my problems not sorted out - it looked like the main-problem were
a) Swap-Partition not big enough
b) disk-encryption (which also stopped me from resizing via GParted)
@mladen It might be an idea to consider increasing the default (OEM) swap-partition to a decent size that general hibernation & hibernation on emergency shutdown due to low battery are working by default (using a premium-priced laptop, one can assume, that such a common feature should be working out of the box).
