Thanks, we start to get a picture. Could you also confirm to us that the output of an lsmod command shows the following modules as loaded:
speedstep_centrino cpufreq_conservative cpufreq_ondemand cpufreq_powersave cpufreq_userspace cpufreq_stats freq_table and that the output of the command (as root): cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver is speedstep_centrino? If you could check dmesg and see what CPU and CPU speed is detected at boot that would also be very helpful. -- CPU monitor reports unrealistic frequencies https://launchpad.net/bugs/94042 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
