[regression-edgy] speedstep-centrino module fails to load

Same problem here after upgrade!
but I'm using a P 4 -M

cat /sys/devices/system/cpu/cpu0/crash_notes
1fe62800

cat /proc/cpuinfo | grep name
model name : Mobile Intel(R) Pentium(R) 4 - M CPU 1.70GHz

As a workaround I got it working when I added "p4-clockmod" to /etc/modules

With this module loaded everything seems to be ok now in /sys/devices/system/cpu/cpu0/
on my system after reboot!

It seems that my problem and the problem of xandl12 are not related.

xandl12 his problem was that the 'p4-clockmod module' is not loaded automatically when the system starts.

In my case it tries to load the speedstep_centrino module (ok) but it fails.

# sudo modprobe speedstep-centrino
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17-10-386/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

# dmesg | tail -1
[17369756.408000] acpi_cpufreq: Unknown symbol cpu_online_map

the bug only occurs in the -386 kernel. I changed to the -generic kernel and it works fine now.

It is the same problem .... I usally don't use the 'p4-clockmod module' but my processor works with tis module too!

I also get normally this message >

when i don't use my workaround method!

Same problem here. It was working with Dapper and after the Edgy upgrade it got broken. Fixed to the max. frequency of 1.73GHz.

That is what I get:

$ cat /proc/cpuinfo | grep name
model name : Intel(R) Pentium(R) M processor 1.73GHz

$ sudo modprobe speedstep-centrino
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17-10-386/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

$ ls /sys/devices/system/cpu/cpu0/
crash_notes

$ sudo cat /sys/devices/system/cpu/cpu0/crash_notes
1ff6c800

Would the workaround with 'p4-clockmod' work with Pentium M?

What kernel are you running (uname -a) ?

If does not end on -generic, you shoul reboot and choose the -generic kernel flavour. speedstep-centrino works fine in that kernel. If it's not available in grub:

apt-get install linux-image-generic

I can confirm that this is a 'linux-image-2.6.17-10-386'-only problem.

The linux-image-2.6.17-10-generic has no such problem and scales the frequency down to 800MHz and up when needed.

As a side effect the cooling fan is not working so often as earlier, I think it depends on the frequency as well as on temperature.

I am having the same problem when using THE GENERIC KERNEL. CPU is intel core2 duo T2300E. Loading the p4-clockmod module (by running sudo modprobe p4-clockmod in terminal) didn't work for me: I got an error message similar to the one which occurs when trying to load the speedstep module.
Currently the only solution for me is using the 686 kernel.

I compiled myself kernel2 2.6.17-13 (ubuntu-patched) and 2.6.19.1 and they both have the same problem:

I receive an error message in /var/log/kern.log
  acpi_cpufreq: Unknown symbol cpu_online_map

I cannot use any cpu frequency scaling feature.

I tride the p4-clockmod, smp, but nothing worked.

The generic kernel works ok, but i still haven't find what is the distictive difference that makes it work.

Hi!

Similar problem to me: I run Kubuntu Edgy, with a customized 2.6.17.14 kernel, on my Centrino laptop (Compal DL76):

$ cat /proc/cpuinfo | grep name
model name : Intel(R) Pentium(R) M processor 1.86GHz

In dmesg I see the same error message:

[xxx.xxx] acpi_cpufreq: Unknown symbol cpu_online_map

I also get the following error:

$ sudo modprobe speedstep-centrino
Password:
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17.14-ubuntu1-custom/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

Furthermore, the directory /sys/devices/system/cpu/cpu0/ is empty (no crash_notes file is there). As a consequence, I have no control on cpufreq profiles.

Note: before kernel compilation, I've been using a 2.6.17-11-generic kernel that worked fine.

Any idea of what is missing? Parhaps some kernel option? I can post my kernel's .config if necessary.
Thank you in advance.

Hi,

I'm sorry to dissapoint you, but i didn't manage to trace the exact
cause, although i managed to fix it!

It definitely requires SMP on!
It might be necessary to include more debug symbols on ACPI, but i
really can't remember what it was that made it work. Just after some
trials-n-errors i managed it....

I'm also affected by this bug, with a Core 2 Duo and -genereric kernel. It did work earlier on edgy, so i dont know when it broke, probably 2.6.17.11?

@Kostis,

I think SMP affects dual-core processors only. I tried enabling that option for my Centrino too, but I got the same error:

FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17.14-ubuntu1-custom/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

Anyway, could you please attach your kernel's .config file ?
Many thx

Yes, i'm attaching it. If it does not get past the mailerman, tell me.

Attaching my kernel config.

Many thanks, Kostis!
At the end I left the SMP option enabled and I got back frequency scaling with the acpi_cpufreq driver. Still no way to have speedstep_centrino working.
I also tried to load the module with debugging on, resulting in the following lines in the kernel's log:

Now I'm trying to contact the developer, as suggested...

Same problem on 2.6.20-15-generic and on the i386 flavour.
Here is some output: felix@felix-laptop:~$ sudo cat /sys/devices/system/cpu/cpu0/crash_notes
1b5f800
felix@felix-laptop:~$ cat /proc/cpuinfo | grep name
model name : Intel(R) Pentium(R) M processor 1.70GHz (note: overclocked by pinmodding to 2266 MHZ)

I can get frequency-scaling working with acpi-cpufreq but not voltage setting even though I patched the kernel with phc and tried to use a modified speedstep-centrino.ko.

The only module I can load from the cpufreq folder except acpi-cpufreq ist speedstep-lib.ko which doesn't work either. I already tried various speedstep-centrino.ko files - even some that I compiled myself and a no-sources 2.6.20 kernel which showed the same problem though it all worked great in dapper drake.

Just FYI, I learned from the Cpufreq list on linux.org that module speedstep centrino is deprecated in 2.6.20 onwards. You should use acpi-cpufreq only.

i had to use the -generic Dapper kernel, but the standard -386 feisty kernel does not exibit the bug anymore. for me it is solved.

We are sorry that we didn't get to your bug report earlier, but the 18 month support period for Edgy Eft, 6.10, has reached it's end of life and we are marking the linux-source-2.6.17 task as Won't fix.
