Hello everybody,
My problem: cpufreq doesn't work at all:
utumno:/home/leszek# cpufreq-info
cpufrequtils 004: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to cpufreq@xxxxxxxxxxxxxxxxxx, please.
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU
analyzing CPU 1:
no or unknown cpufreq driver is active on this CPU
( BTW: cpufreq@xxxxxxxxxxxxxxxxxx bounces! )
Here's a snipplet from dmesg, looks like ACPI doesn't even see that the
processor supports any C-states or any throttling:
[ 1.107335] ACPI: PNP0C0B:00 is registered as cooling_device0
[ 1.107335] ACPI: Fan [FAN] (on)
[ 1.111327] ACPI: ACPI0007:00 is registered as cooling_device1
[ 1.111327] ACPI: ACPI0007:01 is registered as cooling_device2
[ 1.111327] ACPI: Expecting a [Reference] package element, found type 0
[ 1.111327] ACPI: LNXTHERM:01 is registered as thermal_zone0
[ 1.111327] ACPI: Thermal Zone [THRM] (40 C)
( in my laptop, where cpufreq works, precisely at this point ACPI reports about
the C states my laptop processor supports )
I would be very thankful for tips how to debug this case. For starters, I would
like to be able to point my finger at the guilty party: is it the processor,
the mobo, the kernel or my misconfiguration?
