Captured system state during high cpu load by gnome-session in tar bz2

The problem happens off & on but after a boot.I don't remember if it happened after a relogin, I will keep an eye on that & report if necessary.

In an instance of this problem where a login to cinnamon hung, I captured some system state which may be useful. Attaching the same as tar/bzip2 file.

Another user experienced a similar problem:

I have a laptop with connected external display as primary.
I've unpluged external display from laptop. Waited few seconds, Gnome didn't switch laptop display to become primary.
I hit a button to switch displays (named CRT/LCD). Finally laptop display became primary.
In few hours I've connected external display back. Desktop became unrespnosive.
 In few _minutes_ I hit Ctrl-Alt-F2, logged in and restarted gdm (service gdm restart).
After I've logged into GUI there was two gnome-shell processes, one of which died later.
It seems that the core is from this dead gnome-shell.

This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.

Removing old aliases; sorry for the noise.
