Frequency scaling showing wrong frequencies Intrepid C2D
I am having trouble with frequency scaling in ubuntu 8.10. It is only showing 2 available frequencies as 600mhz and 700mhz. I searched the web and found nothing that seems to help my case. So I write to my fellow linuxquestion friends and hope they have an answer. I will provide a few things but let me know what else you need.
$lsmod | grep cpu
Code:
acpi_cpufreq 15500 0
cpufreq_ondemand 14988 2
cpufreq_powersave 9856 0
cpufreq_conservative 14600 0
cpufreq_stats 13188 0
freq_table 12672 3 acpi_cpufreq,cpufreq_ondemand,cpufreq_stats
cpufreq_userspace 11396 0
processor 42156 2 acpi_cpufreq,thermal
$sudo cpufreq-info
Code:
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 600 MHz - 700 MHz
available frequency steps: 700 MHz, 600 MHz
available cpufreq governors: ondemand, powersave, conservative, userspace, performance
current policy: frequency should be within 600 MHz and 700 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 600 MHz (asserted by call to hardware).
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 1
hardware limits: 600 MHz - 700 MHz
available frequency steps: 700 MHz, 600 MHz
available cpufreq governors: ondemand, powersave, conservative, userspace, performance
current policy: frequency should be within 600 MHz and 700 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 600 MHz (asserted by call to hardware).
a section of dmesg that I thought might be of need
Code:

I will provide anything else necessary. Scaling seems to work fine between the two detected frequencies. I almost forgot to add this:
