Comment 1 chanueting 2009-05-10 08:44:12 UTC
GNOME CPU Frequency Applet is used instead of gnome-sensor-applet. Sorry for type error.

Comment 2 Chuck Ebbert 2009-05-21 00:52:18 UTC
What command are you running from the terminal to change the frequency?

Comment 3 chanueting 2009-05-22 07:52:49 UTC
I don't type any command to change the frequency, but the kernel module changes the frequency, while the ondemand mode is set as default.

In the original report you said

"Steps to Reproduce:
1.Changing the cpu frequency by either terminal using echo or through
gnome-sensor-applet"

How were you using echo in a terminal that caused the problem?

Comment 5 chanueting 2009-05-23 05:05:31 UTC
Sorry for the indistinctness in my text above. I think I should describe the situation again. I turn on the Cool n quiet on my motherboard. With the default setting with ondemand mode. My system would crash after I start programs which would make the CPU frequency changes. I tried to select the ondemand mode manually using modprobe and also GNOME CPU Frequency Applet do not solve this problem.

Comment 6 chanueting 2009-05-23 05:26:21 UTC
Sorry for the typos, I was just going to state that I change the frequency using "echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor"

Comment 7 Bug Zapper 2009-11-18 11:55:50 UTC
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bug reports from releases that are no longer maintained.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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 8 Bug Zapper 2009-12-18 09:25:02 UTC
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.
