Description of problem:
Resuming after hibernation reboots back to grub.

Version-Release number of selected component (if applicable):
4.7.6

How reproducible:
Always.

Steps to Reproduce:
1. Hibernate
2. Start computer

Actual results:
The resume image is loaded, system reboots back to grub.

Expected results:
After loading the resume image, the system should resume from where it was prior hibernation.

Additional info:
Resuming used to work up to and including kernel version 4.7.2

Suspending (and resuming from it) works 100%.

I have removed the "quiet" kernel argument, so I can see the resume image being loaded 100%, then some message about console, the screen goes black, and the system is soon back to grub.

I'm doing hibernation using the following commands:
echo shutdown > /sys/power/disk
echo disk > /sys/power/state
This is because the default method for /sys/power/disk hasn't worked reliably in the past.

Hardware: i7-4770k cpu, 32g ram, asus h97-pro motherboard, nvidia gtx750ti gpu

I'm using nvidia driver from rpmfusion:
# rpm -qa | grep -i nvidia

I've added resume and some nvidia commandline arguments to /etc/default/grub:
GRUB_CMDLINE_LINUX="resume=/dev/sda5 nouveau.modeset=0 rd.driver.blacklist=nouveau video=vesa:off"
# cat /proc/cmdline
