>>>>> Francesco wrote: I have installed Debian testing on a X1 Carbon, processor i5-3427U. My problem is the following: when the `ondemand' governor is active, the processor clock never scales up, it always stays at 800Mhz. The situation changes when using the `conservative' or the `performance' governors. More curiously, if I set `conservative'/`performance' as the governor for at least one core, the CPU will scale. I am on the 3.6.6-trunk-amd64 kernel from experimental because the intel video driver 3.2 causes random freezes. To test if the scaling occurs I run `stress -c 4'. Things I have tried: * Enabling/disabling `cpufreqd', `laptop-mode', and `acpid'. I currently run `laptop-mode'. * The 3.2 kernel in testing * Enabling/disabling the `xfce4-power-manager', which I use to manage suspends/hibernate. There are some kind-of relevant BIOS options and I will try with those soon but I doubt that's the issue. Does anybody have any idea on how to troubleshoot such a problem? I suspect that the problem is either in the kernel or in some other software which is regulating the scaling. <<<<< >>>>> > At a guess, I would assume a configuration problem. Or no problem.
