CPU at full frequency after kernel upgrade ["Solved"]

I have upgraded from kernel 3.10 to 3.11.1-1 and now my CPU is at 1.9 Ghz all time.

I have no

 /sys/devices/system/cpu/cpu0/cpufreq 

and https://wiki.archlinux.org/index.php/CP … ncy_driver says that I should use acpi-cpufreq instead of powernow-k8 (I have an AMD cpu) but when I try to load acpi-cpufreq I get

modprobe: ERROR: could not insert 'acpi_cpufreq': No such device

loading powernow-k8 everything goes fine but the wiki says that this module is deprecated and I don't know if I was using this module in the old kernel and why this happened.

Did you reboot after kernel update?

What's the output of

ls /lib/modules/$(uname -r)/kernel/drivers/cpufreq/

?

it seems systemd needs to be updated to  alater version then 204, see https://bbs.archlinux.org/viewtopic.php?id=169372 .

systemd 207 is in testing, you could try that one.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Same problem here. Installed systemd 207-2  from testing, rebooted and problem is fixed.
