Red Hat Bugzilla – Bug 449949
irqbalance documentation for 2 or less cpus
Last modified: 2009-12-18 01:11:46 EST
+++ This bug was initially created as a clone of Bug #442897 +++
Description of problem:
When irq runs on a system with two cpus, it quickly exits not reporting any
reason as to why. Practically speaking, irqbalance doesn't have much work to do
on a system that has only one cache domain and it's job is to spread irq's
across the available domains in the system. However, this will cause confusion
in the minority of our customers and will trigger some support calls. To avoid
confusion I propose documentation that describes expected behavior on systems
with only one cache domain and possibly a pointer to the documentation @ the
irqbalance project page.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run irqbalance on a system with <= 2 cpus or 1 cache domain
2. Check daemon status after a few seconds
Continues to run or report it has nothing to do.

This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
More information and reason for this action is here:
This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10. 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bug reports from releases that are no longer maintained.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 '10'.
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 10'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 10 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:
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 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.
