Red Hat Bugzilla – Bug 233701
nash-hotplug doesn't terminate itself
Last modified: 2011-04-28 14:15:20 EDT
Description of problem:
After /sbin/init is executed, nash-hotplug is still running and needs to be
killed in rc.sysinit.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. comment out line that kills $nashpid in /etc/rc.sysinit
nash-hotplug is running and eating all cpu time
no sign of nash-hotplug
Are you still seeing this in F8+?
I see code in nash to kill hotplug before nash completes. Pretty sure this is
fixed before F8.
Actually, this still might be a problem for the bashbranch. Keeping open for now.
Still reproducible in F8 and rawhide.
Changing version to '9' as part of upcoming Fedora 9 GA.

nash-hotplug showing in powertop
I don't know if this is related to this bug report but I see nash-hotplug
showing up high in powertop stats on my laptop. The thing is that I don't see
nash-hotplug running on my system (according to ps) and I can't find that
binary installed anywhere on my hard drive.
I Attached the powertop log showing nash-hotplug as the worst offender and it
is probably the culprit of rising <kernel IPI> interrupts too.
How can I stop it? I don't want it running on my system.
How can I get the real PID of that thing?
My laptop is running a Fedora 8 system with the latest updates.
please consider this patch from a colleague, not sure it is correct,
but it solved the problem.

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bug reports from releases that are no longer maintained.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:
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.
