Error inserting acpi_cpufreq: Input/output error?

Hi,
I'm trying to set up frequency scaling on my Intel i5 760 as per the wiki.
The only problem is I can't seem to load the acpi_cpufreq module!

# modprobe acpi_cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.39-ARCH/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko.gz): Input/output error

There is no additional output in dmesg from this error.

I'm running x86_64 btw, and I notice that it's trying to load an x86 module, could this have anything to do with it?

Thanks!

Re: Error inserting acpi_cpufreq: Input/output error?

Hi

Did you find a solution? I'm having exactly the same problem with acpi-cpufreq. (eeepc 900). I tried modprobing the p4_clockmod as well, which some older posts say is required for my machine, but I got the same error.

Both modules appear to be available -

ls /lib/modules/$(uname -r)/kernel/arch/x86/kernel/cpu/cpufreq/
acpi-cpufreq.ko.gz     gx-suspmod.ko.gz  mperf.ko.gz        powernow-k6.ko.gz  speedstep-ich.ko.gz
cpufreq-nforce2.ko.gz  longhaul.ko.gz    p4-clockmod.ko.gz  powernow-k7.ko.gz  speedstep-lib.ko.gz
e_powersaver.ko.gz     longrun.ko.gz     pcc-cpufreq.ko.gz  powernow-k8.ko.gz  speedstep-smi.ko.gz

@op - I believe this means that your hardware doesn't support the option.  What kernel version are you running?

Re: Error inserting acpi_cpufreq: Input/output error?

From his error message it looks like he's using the same as me, ie 2.6.39-ARCH (which seems strange since it seems to have only been released today in the ARCH repositories). Based on your hint I am going to try booting into 2.6.38 fallback and see if I can install it (my other machines on 2.6.38 have it installed).

Edit - My fallback kernel is also 2.6.39. Tried modprobing anyway and got the same error.

(Strange re 2.6.38/39. I Suy'd one of my other machines today, a few hours before Suy'ing this one (which resuted in new kernel install) and that other machine is still on 2.6.38.)

not strange, probably different mirrors

Re: Error inserting acpi_cpufreq: Input/output error?

OK. Solved for me. (Mods - Can you mark as solved if appropriate please (as OP hasn't confirmed if solved) ?)

I rolled back my kernel to 2.6.38 from cache and rebooted. Got a "no such device error" trying to modprobe acpi-cpufreq. So moprobed p4-clockmod which installed. (For some reason I can't change it from performance to ondemand, but that's obviously a different issue which I have to investigate).

Presumably I now need to stop my kernel from upgrading if I want this to continue working.

Is there a way of logging a bug report against the kernel (or checking what has been logged) regarding this issue?

Thanks for the help.

Re: Error inserting acpi_cpufreq: Input/output error?

On my x86_64 laptop, I will add acpi-cpufreq to the kernel line - IF I am WITHOUT a battery - because it causes issues on boot otherwise.
So when I am totally on AC without the battery (in), I do not add acpi-cpufreq to the kernel line.

Sometimes I need need to reboot once after I put the battery in.

What was the outcome here actually?

Nothing so far. No responses as you can see and I'm still on the old kernel and haven't yet investigated how to find out if this is a new kernel issue that is is meant to be (and there is some alternative approach) or if it is actually a bug in the kernel (which would surprise me) - and if so whether it has been reported (which I would be surprised if it hasn't been).

Thanks. I used p4-clockmod for kernel 2.6.39 to solve the same issue (eeepc701). I read elsewhere that ondemand was disabled for p4-clockmod as the module's latency is too long to allow it to respond "on-demand".

No solution? I am having the same issue! Used to work great before!

Re: Error inserting acpi_cpufreq: Input/output error?

Hi,
it seems to be the same Problem I had. My solution was to turn on speedstepping and CPU Thermal Trottling in the bios, perhaps you had also turned it off.

Now I have only a Problem with fast running fan while themperature on the CPU is low. There are no more edvanced switches in the bios.

Re: Error inserting acpi_cpufreq: Input/output error?

i had the same error and the problem for me was that i had overclocked my core2duo

for some reason the module refuses to load then. After i set the default options for clock freq and everything in the BIOS, the module did finally load. Of course EIST needs to be enabled too.

p4-clockmod obviously does not care whether the cpu is overclocked or not and will load anyway
