Hi Viresh,

In addition to what I wrote earlier:

I can also make the conservative governor work under the
intel_cpufreq scaling driver, with the default 500 uSec
sampling time, by increasing the
/sys/devices/system/cpu/cpufreq/conservative/freq_step
value from the default of 5 to 100.

In this case there is not a specific break point freq_step,
but rather a very gradual increase in CPU freq as a function
of freq_step for a 100% load on a CPU.

Now, I wonder if the two issues here might be related after all.

... Doug
