** Description changed: This behavior is very inconsistent. I'm using btrfs, which only recently received swap file support as of linux kernel version 5.0. I followed the directions to get a swap file working on btrfs, including using resume=swap_device and resume_offset=swap_file_offset. The physical offset was retrieved using this script: https://github.com/osandov /osandov-linux/blob/master/scripts/btrfs_map_physical.c. I then divided the physical offset by the page size to get the resume offset. At best, hibernating into a swap file only works the first time after creation. Every subsequent hibernation leads my system to boot as if it were not resuming. At worst, hibernating causes the backing device to unattach from the caching device, leading to an unbootable system. I then have to - forcefully recreate the cache in order to fix it. + forcefully recreate the cache in order to fix it.
