How do you read the possible cpu frequencies? Your kernel needs cpufreq support and ondemand, powersave, etc. governors; check with cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors cat /sys/devices/system/cp

Greetings, According to the spec sheet on the Atom N450 it has a single core, though it does support two threads. However, linuxinfo (replaces cpuinfo I suppose) says two unknown processors. r...@hpm210:/home/arthur/Misc/Linux/2.6.34-1# linuxinfo Linux HPm210 2.6.32-5-686 #1 SMP Tue Jun 1 04:59:4
