I have the above problem resulting in laptop failing to restore from hibernation. It starts a fresh session without restoring previous gnome desktop session. Also see: https://ask.fedoraproject.org/en/question/39280/hibernation-problem-acpi-error-installing-cmos-rtc-region-handler/
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs. Fedora 20 has now been rebased to 3.14.4-200.fc20. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those.
Still present with 3.14.4-200.fc20.
Still present with 3.15.6-200.fc20
Created attachment 923635 [details] Outputs of "journalctl -alfxm -o verbose --system --user" around the bug (across a period of 15 minutes) Still present with 3.15.7-200.fc20 I get the message when I close the lid to start the suspend process. Then the suspend doesn't get through, it seems the CPU is in a soft-lockup state. When I try to resume the session (after 1, 5, 10, 15, 20, 30 minutes -- always the same behavior) I am locked outside the GUI but I can use the virtual terminals on Ctrl-Alt-F2 (though I cannot start another GUI instance). I am attaching systemd logs obtained by running > journalctl -alfxm -o verbose --system --user > /data/logs using the default settings in /etc/systemd/journald.conf on a freshly booted-up system with only a Gnome Terminal opened (which runs only that command). No default start applications so I only have what Gnome starts up with beside this terminal. I'll be posting as comments parts of the logs that I find strange/revealing clues: 1. lid closed at 10:15:03.074687 ACPI: Error installing CMOS-RTC region handler i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment ivb_uncore 0000:00:00.0: no hotplug settings from platform <info> sleep requested (sleeping: no enabled: yes) <info> sleeping or disabling... ivb_uncore 0000:00:00.0: using default PCI settings pcieport 0000:00:01.0: no hotplug settings from platform nouveau 0000:01:00.0: no hotplug settings from platform i915 0000:00:02.0: no hotplug settings from platform (and so on for a whole bunch of modules) 2. system state suspend entered at 10:15:06.407293 Suspending system...

Lid opened at 10:30:54.953261 I get the same messages as in 1.

Sadly, the previous session is lost (in this case it was empty anyway).
This bug is still happening for me on kernel 3.15.10-200.fc20.x86_64 and I suspect is the reason hibernate will not resume but always boot normally. Does not seem to cause any other problems I've noticed yet. May also explain why my messages from boot are an hour ahead of actual system time!
I have this issue with 3.15.10-200.fc20.x86_64 on an HP dv6-6173cl laptop. However I just tried hibernating, which I don't normally do, and it worked fine. As yet I have seen no effects apart from the message on boot.
Still present on kernel 3.15.10-201.fc20.x86_64
