Hallo
Ich habe Probleme mit speedstep.
Nichts. Jetzt dachte ich, ich könnte DSDT aus dem Bios auslesen und die Tabelle beim Booten laden.
Ich habe das mal bei meinenm Ubuntu Testsystem geladen.
reboot
Hat nichts gebracht. Die Tabelle ist wohl nicht korrekt. Oben wurde ja ohne Fehler kompilliert. Aber der Takt pendelt nach wie vor zwichen 600 und 800 MHz. Sollte doch aber irgendwo zwischen 2 und 2,66 GHz pendeln. Dazu müßte wohl die DSDT manuell überarbeitet werden? Das ist mir zu hoch.
Ich habe Probleme mit speedstep.
