Hi, I am getting the same issue. Seems to me that the /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq file is set incorrectly to the highest value. Hope the below is of use. --- mark@titanic:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 2793000 2660000 2527000 2394000 2261000 2128000 1995000 1862000 1729000 1596000 1463000 1330000 1197000 mark@titanic:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq 2793000 *********** wrong. Should be the lowest value - 1197000 for me *********** mark@titanic:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 2793000 uname -a: Linux titanic 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux cpufreq-info: cpufrequtils 005: cpufreq-info (C) Dominik Brodowski 2004-2006 Report errors and bugs to
