Not a good sign. This typically means the BIOS tables that list
the est states are missing, or that the chip lacks est completely.
Can you attach the output of /proc/cpuinfo and dmesg ?
The verbose error message should be silent in my work-in-progress
update kernel.
I've noticed that Fedora doesn't include the
speedstep-centrino.ko module.
Normally it would be located in:
/lib/modules/2.6.18-1.2798.fc6/kernel/arch/i386/kernel/cpu/cpufreq/
Would this be the issue?
It's built-in. We have a bunch of built-ins that get their init
routines called one by one, until one 'sticks'. If we get all the
way to userspace and we still haven't got a working cpufreq driver,
we try acpi-cpufreq as a last resort.
There's a few bugs in Bugzilla if you search for acpi_cpufreq in
Summary.
This bug prevents the CPU from stepping down the lower speed (thus running
all the time at the full speed).
When was the last time this worked for you?
