1. Before the 3.10.x line, the computer required hpet=disable highres=off nohz=off in order to resume.
2. With the 3.10.x kernel, suspend/resume worked out of the box.
3. Suspend/resume still works with Debian Sid (3.16.x) and Fedora 21 (3.17.x).
4. The grub command line above no longer works.
5. Using kernel v4.0-rc3 did not solve the problem.
