Hi
I am having problems on my media box, it used to be able to play hd
stuff easily, recently it has been having problems.
I believe I have tracked down the problem to cpufreq-utils.
analyzing CPU 3:
driver: powernow-k8
CPUs which run at the same hardware frequency: 3
CPUs which need to have their frequency coordinated by software: 3
maximum transition latency: 8.0 us.
hardware limits: 800 MHz - 3.00 GHz
available frequency steps: 3.00 GHz, 2.30 GHz, 1.80 GHz, 800 MHz
available cpufreq governors: powersave, conservative, userspace,
ondemand, performance
current policy: frequency should be within 800 MHz and 3.00 GHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
cpufreq stats: 3.00 GHz:89.00%, 2.30 GHz:0.02%, 1.80 GHz:0.07%, 800
MHz:10.91% (3833)
I have tried setting the governor to performance and when I did this
before this line would be different
current CPU frequency is 800 MHz (asserted by call to hardware).
I have tried setting the governor to userspace and setting
/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed
the line stays the same, the stats go up for the rite hz, but I don't
think I am getting the performance I should be :(

I'd check if "preformance" does his job. Try set it with
# cpufreq-set -g performance
and stress the cpu to see if frequency rises, for example by
# yes > /dev/null
Then avoid reboot and try videos.
If everything turned fine check if your setting can sourvive a reboot
and whether your debian needs a fix in his init scripts.
