Subject: Intel Atom N280 cpufreq scaling problem
Date: Thu, 14 May 2009 12:00:54 +0200 [thread overview]
Message-ID: <20090514120054.2e231948.rumi_ml@rtfm.hu> (raw)
Hello there!
I've got a shiny new netbook here with an Atom N280 1.66GHz (667MHz FSB)
currently running Ubuntu 9.04 (Jaunty) from a LiveUSB key and the cpufreq
scaling only scales between 800MHz and 1.33GHz but never sets the maximum
supported speed of 1.66GHz.
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1333000 1066000 800000
# uname -a
Linux ubuntu 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux
This is a relatively new chip released only a few months ago:
http://ark.intel.com/cpu.aspx?groupID=41411
Is this a known problem? Is there maybe a fix?
It could be due to my insufficient g00gling skills but I couldn't
find anything about this issue so far...
Thanks,
Sab
