Description Thomas Müller 2008-04-23 07:39:18 UTC
Description of problem:
powertop suggests to call hal-disable-polling even though polling is already
disabled for all drives


Version-Release number of selected component (if applicable):
powertop-1.9-3.fc9.x86_64
hal-0.5.11-0.6.rc2.fc9.x86_64

How reproducible:
always

Steps to Reproduce:
1. disable polling for all drives
2. run powertop

Actual results:
powertop suggests to call hal-disable-polling

Expected results:
powertop should detect that polling is already disabled

Additional info:
powertop suggests to disable polling on device /dev/scd0.
However, scd0 is just a symlink to sr0 and polling on sr0 is disabled.

Comment 1 Thomas Müller 2008-05-14 07:49:23 UTC
As additional information:

I just pulled the upstream svn repository and it also (wrongly) suggests to call
hal-disable-polling.

Comment 2 Thomas Müller 2008-05-14 08:33:48 UTC
Hmm... I guess it's because of hal's new behavior.

Older versions of hal killed the hald-addon-storage process when polling was
disabled. Now there is a hald-addon-storage process running for every relevant
device, even if polling is disabled on all of them.

powertop then detects these processes and suggests to disable polling. 

Comment 3 Bug Zapper 2008-05-14 10:00:28 UTC
Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:

Comment 4 Bug Zapper 2009-06-10 00:22:35 UTC
This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  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bug reports from releases that are no longer maintained.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 '9'.

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 9'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 9 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 5 Bug Zapper 2009-07-14 14:58:41 UTC
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
