Marking this as a duplicate of bug 1760106 as it's really the better way
to do this than add more parameters into everyone's default kernel
command line.

Title:
  Default kernel command line doesn't work with swapfiles

Status in grub2 package in Ubuntu:
  New

Bug description:
  Currently hibernating doesn't work in the out of box configuration of
  Ubuntu which creates a swapfile by default.

  Swapfiles are less discoverable than swap partitions from the
  perspective of initramfs-tools and the kernel.

  To use them the following kernel command line options are needed:
  resume=
  resume_offset=

  Resume represents the device that will be resumed from that contains the swapfile.
  Resume offset represents the location in the disk that the swapfile is located.

  
  Attached is a patch that will populate these two options as necessary
