I also have this problem and just applied the patch from the kernel mailinglist to the 4.17.5 release. After that, resume works fine. I have attached a patch to the PKGBUILD file.

UPDATE: I meant 4.17.5 not 4.15.5

The patch landed in the 4.18.5 kernel, which is already in "staging", so I think this bug can be closed soon.
