BTRFS in 4.4.0-rc7 keeping system from hibernating
Hello, Ever since 4.4.0-rc1 or so, BTRFS and XFS hasn't played well with hibernation. It may be deeper down as both filesystems seem to have issues with not being able to commit/freeze as can be seen below: [81167.893207] PM: Syncing filesystems ... done.
