If I remember correctly resume was set to cryptswap partition. When doing so again (`RESUME=UUID=xxx`) invocation of `update-initramfs -uk all` gives
``` W: initramfs-tools configuration sets RESUME=UUID=9792e199-e275-4547-b9ce-c4e507e8bd5d W: but no matching swap device is available. ```
The device is available and in use.
