Hi, I have just tested it on Pangolin beta-2 (64), and it's still an issue there.
I have AMD C-60, with Turbo Core. CPU frequency should be able to reach maximum 1300MHz, but it never does. The biggest frequency I was able to get under any circumstance was just 1000MHz (I'm using turbostat to calculate real current CPU clock). $ uname -a Linux ubuntu 3.2.0-20-generic #33-Ubuntu SMP Tue Mar 27 16:42:26 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies 1000000 800000 $ dmesg | grep powernow [ 10.706261] powernow-k8: Found 1 AMD C-60 APU with Radeon(tm) HD Graphics (2 cpu cores) (version 2.20.00) [ 10.706286] powernow-k8: Core Performance Boosting: on.
