Description Henrik Nordström 2011-09-04 20:27:00 UTC
Description of problem:

Fails to build if cpufreq scaling is enabled

Version-Release number of selected component (if applicable):


How reproducible:

always with cpufreq scaling enabled, even if running at max frequency

Steps to Reproduce:
1. cpufreq governor set to anything else than performance
Actual results:

Build fails with

CPU Throttling apparently enabled!
It appears you have cpu throttling enabled, which makes timings
unreliable and an ATLAS install nonsensical.  Aborting.
See ATLAS/INSTALL.txt for further information
error: Bad exit status from /var/tmp/rpm-tmp.v5rcmF (%build)

Expected results:

Build continue anyway.

Additional info:

Earlier versions did override this by using a configure flag
  -Si cputhrchk 0
which was removed in this package version because "upstream frowns at it".

Requiring this specific build conditions for a distro-wide binary build do not make much sense. There is no guarantee koji hosts will have cpufreq disabled, and any measurements done by the package will anyway only be matching the koji hosts and most likely very load dependent and unpreductable anyway. If this package needs to perform such detailed hardware measurements it's better provided with a preconfigured hardware profile making builds reproducible and controllable.

Comment 1 Fedora End Of Life 2012-08-07 15:51:26 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

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

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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 to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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.

The process we are following is described here:
