I strongly suspect a HW issue.
Patrick, please recheck /etc/default/grub and be sure it is as what you set it to that resulted in successful hibernation and reboot.
All I know is that I changed GRUB_DISABLE_RECOVERY="false" (from "true") and rebooted. That was the only change. When I tried hibernation it worked (i.e. resuming worked). In fact it worked at least twice, then *with no further change* didn't work. Given the random nature of this it's hard to ascribe causality. One can never discount HW of course, but there are no other symptoms. The system is an i7 CPU in an Intel mobo with 16GB of RAM and root on an SSD formatted as btrfs. Video is an Nvidia GeForce GT 630.

Just wondering if anything changed between working and not working; i.e. I check the file again. Other than that, hardware and device drivers might be an issue. In case you are using the Nvidia proprietary driver proprietary driver, then as Ed Greshko pointed out, revert to the fedora driver for the graphics card, and retry.
