This combination is sufficiently incongruent to be utterly broken, and therefore looks a likely blocker in my opinion.

a. It's the default behavior, rather than power off, when battery power is critical https://bugzilla.redhat.com/show_bug.cgi?id=1141345

b. Either systemd or the kernel isn't seeing the hibernation image, or isn't putting the system into hibernation mode, because it just reboots when the user hits the power button trying to resume. Therefore resume doesn't actually happen. https://bugzilla.redhat.com/show_bug.cgi?id=1199708

c. The installer doesn't configure systems for hibernation out of the box.

Until b and c are addressed, the simple fix is to address bug a.

a. is incorrect. We updated UPower, and not gnome-settings-daemon or gnome-control-center.

UPower is now responsible for what to do when the battery level is too low. In /etc/UPower/UPower.conf it says: # The action to take when "TimeAction" or "PercentageAction" above has been # reached for the batteries (UPS or laptop batteries) supplying the computer # # Possible values are: # PowerOff # Hibernate # HybridSleep # # If HybridSleep isn't available, Hibernate will be used # If Hibernate isn't available, PowerOff will be used CriticalPowerAction=HybridSleep

This isn't a user option anymore, and there's no code in gnome-settings-daemon to handle it.

I filed this bug about it: https://bugzilla.gnome.org/show_bug.cgi?id=749436

It's not a blocker though, as it's "just as broken in F21".

Cheers
