cpufreqd won't start after upgrade to 2.6.23 [SOLVED]

I have upgraded my kernel from 2.6.21 to 2.6.23 (gentoo) and cpufreqd will not start any more. Error message is:
"cpufreqd requires the kernel to be configured with CONFIG_CPU_FREQ", but my kernel does have that option enabled:
# zgrep CONFIG_CPU_FREQ /proc/config.gz
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=m
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=m
# CONFIG_CPU_FREQ_STAT_DETAILS is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=m
CONFIG_CPU_FREQ_GOV_USERSPACE=m
CONFIG_CPU_FREQ_GOV_ONDEMAND=m
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m

Hardware is Fujitsu Lifebook S series. Frequency scaling was working well before the upgrade. I reported this a while ago on the cpufreqd sourceforge site but that looks like there is no recent activity there. Any ideas?

I don't have that laptop but I'm on kernel 2.6.23 too.

Can you manually switch frequencies using cpufrequtils, or does that give an error too?

I'm having this very same issue. Did anybody find a solution?

Do you have the correct driver (not governor, but processor specific driver) selected in -> Power management options -> CPU Frequency scaling?

I don't actually know what's the correct driver for me (I used to think it was Intel Enhanced Speedstep) so I compiled every driver built in and now it's working.

Hi,

i've just faced this problem upgrading from 2.6.22 to 2.6.23. I saw some other threads complaining about this issue. I have a pentium-m core with centrino and always used CONFIG_X86_SPEEDSTEP_CENTRINO option. After hours of trying :evil:

i've build the 2.6.24 and saw the following help near the centrino(Intel Enhanced SpeedStep (deprecated) ):

This is deprecated and this functionality is now merged into
acpi_cpufreq (X86_ACPI_CPUFREQ). Use that driver instead of
speedstep_centrino.
This adds the CPUFreq driver for Enhanced SpeedStep enabled
mobile CPUs. This means Intel Pentium M (Centrino) CPUs
or 64bit enabled Intel Xeons.
:!:

this message is one version too late, eh? :lol:

anyway, CONFIG_X86_ACPI_CPUFREQ is now managing centrino cpu's...

greets

i am also having this issue. I have a desktop intel x86_64 pentium D chip. Which option should I have turned on? is it also x86_acpi_cpufreq as well?
