[SOLVED] CPU scaling doesn't work with the new kernel

Michiel · 2006-04-06 08:16:35

I just updated my kernel to 2.6.16.1-7, but now my CPU scaling doesn't work anymore.

root@vanessa ~# modprobe cpufreq_userspace
root@vanessa ~# modprobe speedstep_centrino
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.16-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and the last line of dmesg:

speedstep_centrino: Unknown symbol acpi_processor_preregister_performance

Any ideas? Looks like this is an error in the speedstep_centrino module.. bit. As far as I know I hadn't this error with the -6 kernel package..

same here

removed acpi patch from kernel, seems it breaks speedstep

Michiel · 2006-04-06 19:46:02

Works with the -8 kernel package release (and new powernowd) again

did you anything else except update your kernel version? because the problem isn't gone away here

[cagnulein@cagnulein ~]$ sudo modprobe speedstep_centrino

and powernowd

Please make sure that:
 - You are running a v2.6.7 kernel or later
 - That you have sysfs mounted /sys
 - That you have the core cpufreq and cpufreq-userspace
   modules loaded into your kernel
 - That you have the cpufreq driver for your cpu loaded,
   (for example: powernow-k7), and that it works. Check
   'dmesg' for errors.
If all of the above are true, and you still have problems,

it includes the latest cpufreq from kernel.org, but that hasn't caused any trouble yet.
my question is has this module ever loaded on your pc?

Cagnulein · 2006-04-07 10:44:07

never because i moved to arch 4 days ago

so which modules shall i use?
Thanks.

tpowa · 2006-04-07 12:51:16

do you have a p4 or a centrino?
there are some modules:
/lib/modules/2.6.16-ARCH/kernel/arch/i386/kernel/cpu/cpufreq/
you have to try by hand which is the right for you.

Shouldnt matter,

speedstep_centrino: Unknown symbol acpi_processor_preregister_performance

unknown symbols should not arise, no matter whether the user has that hardware or not. If the user doesnt have speedstep_centrino, it would spit, no such device.

other ideas?

tpowa · 2006-04-08 06:15:35

try all

Cagnulein · 2006-04-08 12:42:59

i've tried all and the only that it works is p4-clockmod, but when i start powernowd it show me wrongs step:

powernowd: PowerNow Daemon v0.97, (c) 2003-2006 John Clemens
powernowd: Found 1 scalable unit:  -- 1 'CPU' per scalable unit
powernowd:   cpu0: 75Mhz - 600Mhz (8 steps)

same thing with cpufreqd...
