Bug 163474

This report targets the FC3 or FC4 products, which have now been EOL'd.

Could you please check that it still applies to a current Fedora release, and
either update the target product or close it ?

Thanks.

The behavior persists in Fedora Core 6, with the entire system "yum update" as
of today, specifically these components which seem relevant:
  hal-0.5.8.1-6.fc6
  kernel-2.6.19-1.2895.fc6
  gnome-desktop-2.16.0-1.fc6
  nautilus-2.16.2-5.fc6
  autofs-5.0.1-0.rc3.6
Namely, an empty IDE CD/DVD drive sees around 9 or 10 interrupts per second, and
a drive with a written disk (iso9660, auto-mounted, otherwise idle) sees about 2
or 3 interrupts per second.  I changed the Version of this bugzilla report to fc6.

If hal is not the appropriate component for this issue, then please suggest a
better culprit.  Also, is there a setting to control the frequency of polling?

Fedora apologizes that these issues have not been resolved yet. We're
sorry it's taken so long for your bug to be properly triaged and acted
on. We appreciate the time you took to report this issue and want to
make sure no important bugs slip through the cracks.

If you're currently running a version of Fedora Core between 1 and 6,
please note that Fedora no longer maintains these releases. We strongly
encourage you to upgrade to a current Fedora release. In order to
refocus our efforts as a project we are flagging all of the open bugs
for releases which are no longer maintained and closing them.

If this bug is still open against Fedora Core 1 through 6, thirty days
from now, it will be closed 'WONTFIX'. If you can reporduce this bug in
the latest Fedora version, please change to the respective version. If
you are unable to do this, please add a comment to this bug requesting
the change.

Thanks for your help, and we apologize again that we haven't handled
these issues to this point.

We will be following the process here:

doesn't happen again.

Please change 'Version' to rawhide; bugzilla won't let me.

The problem persists in rawhide kernel-2.6.25-0.185.rc7.git6.fc9.x86_64.  With
two idle IDE CD/DVD drives, I see 21 interrupts per second:
cat /proc/interrupts | grep 15: ; sleep 10; cat /proc/interupts | grep 15:

"ps ax" says that hald-addon-storage is polling each drive "(every 2 sec)".

I checked the box for "I am providing the requested information" when I
submitted Comment #4 above, but the updated page still has Status: NEEDINFO.

This time I'll check the box again, and _also_ tick the radio button for Change
to Assigned.

changed over to rawhide. 

Let us know if there's anything we can do to help resolve this - this falls into
the category of "we wake up too much".

Changing version to '9' as part of upcoming Fedora 9 GA.

Sure we poll as some drives do not support media detection. I'm not sure what
you want us to do here.

As stated in this original buzilla report, what I want is: "Expected Results: 
Polling frequency should be 1 Hz or less."

Additionally, it would be nice for the system administrator to change the
frequency easily, including setting it to zero (no polling.)

$ ps aux|grep hald-addon-storage
root      2719  0.0  0.0  24172  1116 ?        S    May31   0:01
hald-addon-storage: polling /dev/sr0 (every 2 sec)

Of course this translates into more wakeups etc. from the kernel driver.

$ man hal-disable-polling

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

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.
