Sorry, strangely some information got lost in the mail. Here is another
try to communicate all the info.
Hi to all,
my cpufreq system works perfectly fine when the battery is plugged in.
Nontheless, when I unplug my battery and only leave my AC adapter
plugged in, scaling_max_freq locks to 1000000 although this is
configured nowhere. cpufreqd replies with
I haven't been able to set the chosen policy for CPU0. I set
1667000-1000000-ondemand System says 1000000-1000000-ondemand
cpufreqd_loop : Cannot set policy, Rule unchanged ("none").
When replugging the battery it takes about 40s that scaling_max_freq
reverts to 1667000 and everything works fine again.
I wonder whether this phenomenon has been encountered before and how to
solve it such that my cpu frequencies do not get locked when I have only
my AC adapter plugged in.
Here are my info:
