Could you share which memory and nvme you are using?
Or any tools you use to diagnose what’s active during suspend?
I’m so using stock Fedora 40 with no hibernation. However my system can only suspend for about 1.5 days.
It sleeps through the night and just long enough to last until I get home after work.
I also am used to 14 day suspends (Dell XPS 13 Skylake). But 7+ days would enable me to use the Framework according to my natural browsing habits.
