Can you check with top that no process is running/eating time? If you change cpufreq governor to powersave, will it react? Can you check with powertop if the cpu is idle (C2/C3)or if it is running something? Actually, booting with nosmp might be useful. Is it always same core? -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
