Alright, I am now out of ideas. I have tried the btrfs_map_physical.c script to get the physical offset. I now even have the 'Hibernate' option in the 'KDE Leave' menu. BUT.... When I do a hibernate either via the KDE menu or 'systemctl hibernate', the screen goes blank for 2 seconds and comes back. Hibernation is not successful. This is what I get from 'dmesg': [ 269.976652] PM: Cannot find swap device, try swapon -a [ 269.976655] PM: Cannot get swap writer [ 270.069993] PM: hibernation: Basic memory bitmaps freed [ 270.069997] OOM killer enabled.

This is my output from 'swapon': $ swapon NAME TYPE SIZE USED PRIO /fedora.swap file 10G 0B -2 /dev/zram0 partition 3.8G 27M 100 Patrick said BTRFS have been set up by people here, but I could not find any relevant threads that showed that. So what is going wrong ? Is this a bug ? -- Regards, Sreyan Chakravarty
