Public bug reported:
Since kernel version 2.6.32-25-generic it's not possible any more to change the
CPU to the maximum available of 2,4 GHz. The gnome-cpu-applet shows the
available states (800 MHz, 1,6 GHz, 2,4 GHz), but after clicking "2,4 GHz", the
CPU is running at 1,6 GHz. Selecting the "Performance" option doesn't help
either, still running at 1,6 GHz.
Setting the CPU via "$ cpufreq-selector -c 0 -f 2400000" doesn't work.
Tried the kernel 2.6.35-02063506.201009271105 from the mainline kernel
PPA, but the problem still exists.
Booting with kernel 2.6.32-24-generic, it works.
So I guess it's a regression.
