Hi,
I've played around and studied but I can't figure it out.
I want to set my CPU to hw-max but it always gets ignored. What's wrong?
Some Infos:

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 800 MHz - 2.13 GHz
available frequency steps: 2.13 GHz, 1.87 GHz, 1.60 GHz, 1.33 GHz, 1.07 GHz,
800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave,
performance
current policy: frequency should be within 800 MHz and 1.33 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency is 1.33 GHz (asserted by call to hardware).
cpufreq stats: 2.13 GHz:0.13%, 1.87 GHz:0.00%, 1.60 GHz:0.00%, 1.33
GHz:58.49%, 1.07 GHz:0.05%, 800 MHz:41.33% (585)
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

# cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
800000
Ohhh ... "someone" set the CPU speed down to 800 kHz in the meantime. Why?
Who? Governor is "userspace" ...
# echo "2133000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
1333000
I can't get the MAX frequency set to 2133000 though it's the upper HW-limit.
Therefore I never get 2133000. The computer feels slow and clumsy (yes, it's
an old one ... but most of the time I'm running 0.8 GHz instead of 2.13 GHz)
:(
What's wrong? Some info missing?
