Description Matthew Bunt 2015-01-16 16:22:46 UTC 
Description of problem:
This error was reported to me as the computer first reached GNOME. I have not noticed any odd behavior or other side effects, just the notification stating there was a problem with the kernel and the option to report this bug.

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There are 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 21 kernel bugs.

Fedora 21 has now been rebased to 3.18.3-201.fc21.  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.
Comment 3 Srihari Vijayaraghavan 2015-02-07 00:23:58 UTC 
Description of problem:
It happens only when nVidia/nouvea combination is active. It's rather easily triggered by simply issuing shutdown (or even logout) from within GUI desktop.

Comment 4 Garrett Holmstrom 2015-03-05 01:15:30 UTC 
Description of problem:
This happened shortly after logging into a cinnamon session that went surprisingly far.  Most of the time when I boot the system X doesn't even manage to get running.  nomodeset happens to sidestep this problem.

This happens sometimes during X startup on my W540. I have both Intel and nVidia graphics, though the nVidia graphics sit unused as all outputs are connected to Intel.
Comment 7 Fedora Kernel Team 2015-04-28 18:29:52 UTC 
*********** 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 21 kernel bugs.

Fedora 21 has now been rebased to 3.19.5-200.fc21.  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 have moved on to Fedora 22, and are still experiencing this issue, please change the version to Fedora 22.

If you experience different issues, please open a new bug report for those.

Comment 9 Fedora End Of Life 2015-11-04 11:17:51 UTC 
This message is a reminder that Fedora 21 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 21. 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 '21'.

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 21 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.
Comment 10 Fedora End Of Life 2015-12-02 07:31:55 UTC 
Fedora 21 changed to end-of-life (EOL) status on 2015-12-01. Fedora 21 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.
