MSR_IA32_THERM_CONTROL: 0x0 [Software-controlled clock disabled (full speed)]

[piruthiviraj natarajan]

Recently for the past couple of months I have been noticing that when I
start firefox my system fans go mad and CPU temp rises significantly by at
least 5Celcius. When I use Google plus the CPU usage reaches at least
40-60% and I assume javascript is making the system go crazy. This rarely
happens in chrome though. I found this same behavior in other distros as
well. Debian unstable, Gentoo, arch. I thought if I switched to some recent
versions(stransky's copr
packages)http://copr.fedoraproject.org/coprs/stransky/FirefoxGtk3/of
Firefox 29 would help but to no avail. Did anyone else notice this
kind
of thing on their systems?
I think its specific to recent Intel core processors.
my output of x86info is

What does this software-controlled clock disabled (full speed) mean in this
output? Can I manually enable it again so that system would not run hot
like crazy?

I run fedora rawhide and I forgot to mention that.

Not a "MSR_IA32_THERM_CONTROL" exclusively, however take a look if this
can help,
$ rpm -qil kernel-tools

thanks for the answer.
I use thermald for power control and cpupower is not enabled on my system.
I found thermald only after I found this whole Firefox issue. I am not sure
if Firefox being a big package is augmenting the issue.
https://github.com/01org/thermal_daemon

couldn't find any relevant documentation for the
[Software-controlled clock disabled (full speed)]

All right!
https://bugzilla.redhat.com/show_bug.cgi?id=974714 ;)
http://spandruvada.fedorapeople.org/
BTW you can ask the same Srinivas Pandruvada about
"IA32_CLOCK_MODULATION" aka "MSR_IA32_THERM_CONTROL"
email is in the 'spec',
http://spandruvada.fedorapeople.org/thermal-daemon.spec

You can start from here, :)

And to not go too far, you can try this,
.mozilla/firefox/<PROFILE>/user.js
or
.mozilla/firefox/<PROFILE>/prefs.js
user_pref("network.http.max-connections", 32);

Of course ain't telling you to change the processor.
Haha

I moved to 3.14 kernel today and I added your suggestion to prefs.js and
everything looks cool until now and I shall report back if I get the issues
again. Thanks!

I've noticed this too. I haven't yet understood why it happens. I'll
keep an eye out for FF. Here's what I have:

Did anyone try this for power saving?
