Same issue here, fresh install of stock Ubuntu 17.10(.1) on a ThinkPad X1 Carbon gen5, kernel 4.13.0-25-generic, with LUKS-encrypted swap partition sitting alongside the root partition. The same hardware/setup worked fine on Zesty but as we know, that just went EoL.
Just to add: the machine seems completely frozen at resume based on the keyboard caps-lock LED test. I do get the LUKS password prompt so that part seems fine.
Hibernation is critical functionality from a security standpoint as an alternative to far less secure suspend to RAM functionality.
Please let us know how/if we can help progressing this bug.
