Comment 7 for bug 578952

There are a few packages different, but none of them look relevant. The diff is attached. (The only packages I installed manually on the non-hibernating system are the ssh-related ones.)

One thing I should point out: the "PM: Resume from disk failed" message doesn't only appear when the system should resume but fails to do so; it also appears every time the system boots up normally (when there is no saved image). The meaning of the message is thus more "no image found, proceeding with normal boot" than "uh oh, I tried to resume but something went wrong."

Have you tried to reproduce this bug? I used the alternate installer, with the cli-expert option, to create the minimal system. It should be possible to reproduce this without even installing a full desktop environment---I only did so because of the half-dozen ways to do hibernation in Linux, I was only concerned with the one used by the desktop.
