Hanno Stock,

After a fresh system start "cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver" returns speedstep-smi.

Running /etc/init.d/powernowd stop; cpufreq-selector -g userspace; powernowd -q (as root) returns the laptop to 7.10 style CPU freq scaling (two steps 700/1000 MHz). It seems to work fine until a power state change occurs. Unplugging the AC adapter or plugging it in causes the CPU scaling to lock in 100% mode again.

7.10 simply worked without any special configuration. What changed to cause this?
