I already tried to disable USB, PCMCIA, Network, Framebuffer, Cpufreq etc., but even with a minimalistic system there ist still the following output of /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[00901857] C3: promotion[--] demotion[C2] latency[085] usage[00000000] Is there anything else I can do? Or can I somehow find out, what is causing the bus master activity? Disabling the bm_check=1 in the processor.c code works, but that is probably the wrong solution. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
