Maybe it is possible to set the processor-state of my centrino manually. Can please anybody tell me how to get it right? The reason I'm asking is, that once I do load the processor.ko module, my Centrino switches immediately into C2-state. It never switches back to C1 state, even under heavy load like compiling the kernel. I think the kernel should switch back from C2 to C1 state from alone???? Please ask me whatever you need to help me swtiching back into C1 state. christian cat /proc/acpi/processor/CPU0/power active state: C2 default state: C1 bus master activity: ffffffff states: C1: promotion[C2] demotion[--] latency[000] usage[00000010] *C2: promotion[C3] demotion[C1] latency[001] usage[00905291] C3: promotion[--] demotion[C2] latency[185] usage[00000000] behn-GKM3wtwTCu0@public.gmane.org:~$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 9 model name : Intel(R) Pentium(R) M processor 1600MHz stepping : 5 cpu MHz : 599.964 cache size : 1024 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 apic sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 tm pbe tm2 est bogomips : 1185.79 ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
