It seems you are telling me that server boards often experience issues with suspend/hibernate.. I wasn't aware of that but mine is my first server board..If you start/run your dockers with --restart=always -- google for docs, then they will restart automatically on boot. I think this is more easy to solve than suspend/resume on *server* board.
Yes I could restart the containers automatically at every reboot, but think about the models, the jupyter notebooks inside these containers..
Ultimately I think I can live with restarting everything every time, but it will be boring, and it makes using the ipmi via the internet even more important, since not being able to suspend would equate not to being able to use wake on lan...
