Thank you, Luis sda2 located on SSD and it's my main partition (both / and /home) smartctl -a output is in attached file I've noticed that the probability of failed suspend is higher when I have a running docker container, but this container does nothing with regards to heavy disk i/o. But this may be a coincidence because when this happens usually the next try after stopping the container will also fail. I'm trying to reproduce it with kernel compilation as you suggested
