Description James 2008-07-04 19:05:19 UTC
Description of problem:
powertop (and 1.10) often reports garbage with kernel-2.6.25.9-42.fc8 and
predecessors on this notebook (Intel Core 2 Duo T8100, acpi-cpufreq driver). As
an example:

Wakeups-from-idle per second : -26.2    interval: 0.3s
no ACPI power usage estimate available

Top causes for wakeups:
  37.5% (  inf)      <kernel IPI> : Rescheduling interrupts 
  21.1% (  inf)       <interrupt> : acpi 
  18.0% (  inf)       <interrupt> : uhci_hcd:usb3, sdhc0:slot0, sdhc1:slot0, iwl
   3.1% (  inf)                 X : do_setitimer (it_real_fn) 
   3.1% (  inf)           gkrellm : schedule_timeout (process_timeout) 
   2.3% (  inf)      nash-hotplug : ehci_work (ehci_watchdog) 

I also sometime see nans, absurdly low wups counts, absurd residency
percentages, etc.

Version-Release number of selected component (if applicable):
powertop-1.9-2.fc8

How reproducible:
Always.

Steps to Reproduce:
1. Run powertop.

Actual results:
Untrustworthy numbers.

Expected results:
Sensible numbers.

Comment 1 Bug Zapper 2008-11-26 10:57:42 UTC
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 
'version' of '8'.

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 prior to Fedora 8's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 8 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 please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

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:

Still seeing occasional nonsense in powertop-1.9-3.fc9.x86_64.

Comment 4 Karel Volný 2009-10-20 11:16:17 UTC
please, could you re-test using the current package version?

(I've noticed you changed Fedora version to 11, does that mean that the bug still appears with powertop-1.11-2?)

Comment 6 Bug Zapper 2010-06-28 10:40:40 UTC
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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.

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