I am getting this error sometimes when I resume from hibernation. All of my open windows are closed. There is also an extra reboot before it will actually get to the login screen.
The title of the error as seen in Apport is
[Gigabyte Technology Co., Ltd. To be filled by O.E.M.] hibernate/resume failure [non-free: nvidia]
The annotation says
This occured during a previous hibernate and prevented it from resuming properly.

The https://wiki.ubuntu.com/DebuggingKernelHibernate page isn't helping. My problem doesn't seem to be there. This is not a problem with encrypted swap. It is not encrypted.
I do have an Nvidia GTX 670.
