Description Robert Hancock 2014-09-26 01:51:16 UTC

Comment 11 Robert Hancock 2014-09-26 01:56:21 UTC 
Changing component to microcode_ctl as the update to version 2.1-6 is what introduced the issue. It seems to be the one described in the Debian bug report I added a reference to.

Since this update seems to disable TSX instructions, I am assuming that the solution is that this update can't be installed while software that could be using TSX is running. Or the use of TSX instructions has to be turned off entirely.

See the discussion on https://admin.fedoraproject.org/updates/FEDORA-2014-11178/microcode_ctl-2.1-8.fc21 .

Comment 15 Carlos O'Donell 2014-09-27 16:50:19 UTC 
The tools team is disabling TSX support in glibc because of this issue.

See:
https://bugzilla.redhat.com/show_bug.cgi?id=1146967

So now dracut and kernel do early update, and glibc disables TSX if you can't or don't wnat to upgrade your kernel.

Comment 17 Fedora End Of Life 2015-05-29 12:57:58 UTC 
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bug reports from releases that are no longer maintained.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.
Comment 18 Robert Hancock 2015-05-30 00:10:43 UTC 
This is fixed in 1146967 so marking as a dupe.
