Re: temperature problems

[gusti <ggh.develop@gmail.com>]

Thanks for your answer, but seems like the problem have not relation 
with frequency throttling. I say that because in my system I have not 
control to change these kind of things. I want to say that all the 
frequencies still all the time the same.
More over I tried to active the control of the cpu frequencies but I 
did not success with that, but is OK, I will ask about it in other mail, 
;-).

Thank a lot any way,
       Gustavo
