Hi! I think I solved the problem by building a custom Kernel 2.6.13.4 (from www.kernel.org) with the "/proc/acpi/processor/../performance" interface (deprecated) enabled. Then I deinstalled the "powernowd" and installed the "cpufreqd". Next (after reboot) I ran "dpkg-reconfigure cpufreqd". That's it. Regards oschwa2s -- oschwa2s
