Expected results:
less drama :-)

Additional info:
I'm getting this within a custom Live Fedora built by livecd-tools via koji.  I get two ISO images that are damned near identical where only the architecture is different.  One is i386 and the other x86_64.  I've only seen the problem with the i386 image but that's also where I've done the majority of my testing of late.  I'll flip over to x86_64 to see if I can catch it there.  I suspect I won't given how repeatable it is on i386.

Comment 1 John Florian 2015-09-28 13:48:12 UTC
I only ever see this on i386.  With x86_64 it works as expected.  This may be related to Bug #1188458 on armv7hl.

Any word on a possible fix for F21?

Comment 2 Daniel Brown 2015-10-30 15:56:10 UTC
I am also seeing this issue occur on different timezones. There are some timezones where this does not happen at all. I still have machines that need to be supported for fedeora 21. A fix would be appreciated.

Comment 3 Fedora End Of Life 2015-11-04 10:00:43 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bug reports from releases that are no longer maintained.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 4 Fedora End Of Life 2015-12-02 15:12:18 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no longer maintained, which means that it will not receive any further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.
