It does not do this for me. I have:
menuentry 'LFS (SVN-20140604 on /dev/sda10 hibernate)' {
linux /vmlinuz-3.14.3-lfs20140604 root=/dev/sda10 ro resume=/dev/sda11
}
and hibernate works for me. At least it did when I last tried it from xfce.
As you know, I'm not using systemd, but I am using a standard pci based disk
drive, so I suspect something about that is causing the problem.
