This is with secure boot disabled, big enough swap etc. On my X1C7 the device just shuts down and then it's as if you power cycled it when you power on again. I started poking at it a bit (we even have a RH bug somewhere) but in the end have gone with "hibernate isn't supported" as the way forward. Happy to help with the exercise if there are any pointers or data needed, guineau pig for testing etc. I didn't make much progress the last time I looked at it 😊 I haven't seen much customer demand for it to be honest - but I appreciate the reasons why some would like it.
