    Hi, while testing kpowesave I found that the daemon complained that it is only for AMD K7.
    Trying to start the daemon manually fails. All of this is happening on a centrino notebook
    What gives?

    Thanks

      Where does it complain and how does this message look like?

      What's that for a notebook?

      Is the speedstep driver loaded(e.g. speedstep_centrino)?

      Thanks for the fast reply.
      It' s toshiba notebook with an centrino cpu
      It complains at bootime and says something like
      powersave(something): This will work only on AMD K7

      No, no speedstep driver is loaded

      (sorry for not being more precise but i had to uninstall it for now and)

      Thanks again

        Which distribution? If it is SUSE or you at least use the init script which comes with powersaved, this script should load the speedstep_centrino module. Otherwise make sure that all relevant cpufreq modules (speedstep_centrino, cpufreq_ondemand, ...) are loaded before powersaved is started. I can't find such an error message at any place in the code/scripts though.

        Regards,

        • The message is from the powernow-k7 module:
          root@strolchi:~# modprobe powernow-k7; dmesg|tail -n 1
          FATAL: Error inserting powernow_k7 (/lib/modules/2.6.16.13-4-default/kernel/arch/i386/kernel/cpu/cpufreq/powernow-k7.ko): No such device
          powernow: This module only works with AMD K7 CPUs

          Since the default script loads all modules until a matching one is found, this leads to this message. However, it is totally harmless.

          You should check, why the speedstep-centrino module does not work for you, maybe check the output of the "cpufreq-info" command from the cpufrequtils, there might be some hints.

      OK fixed,
      It was an total different problem afterall.
      I had to add the user to the powerdev group to make it work.
      I found this out after doing a ps -aux and finding that powersaved was running.
      I just got confused by
      1. error message at bootime
      2. error message when doing a /etc/init.d/powersaved start. (that plain "failed" message was not much of an help)
      3. By the error message of kpowesave telling me powersave was not running. (Maybe adding a message like " check user is in powerdev group" would help many users)

      Thanks everyone for helping
      Btw the module that get's loaded during boottime is called speedstep_lib (or something like that, I can check if you want when I get back on the notebook) So maybe it could be usefull it powersaved looked for that module before telling the user of  "only works with AMD K7 CPUs "

      My 2c

      Thanks again
