hi, morning to all,

was afraid about following message:

[root@dhcppc0 ~]# modprobe acpi

I tried:

first

changed the line below in /etc/cpuspeed.conf:

DRIVER=powernow-k8

with no response

then add acpi=off in the /boot/grub/grub.conf file

and there is also no response, the error message still appears


i´m very confused about this

searched the web over for fusi modules + linux

can not find any useful articles or other sources


if anybody is aware of useful links to the subject of acpi
please quote


thanks to all

martin

Can’t help much, but the DRIVER= statement change you made would only be correct for an AMD processor, and, from your post, you have an Intel Centrino. You could try DRIVER=p4-clockmod, but the comments in /etc/cpuspeed.conf say that the proper driver should be autodetected, and already be in the kernel.

When you runyou should see something like this:but that’s with cpuspee active.

thanks,

have done

first

cpuspeed is active

second

DRIVER= ( set on autodedect )

but the error message still appears

cat /proc...tells me


[martin@dhcppc0 ~]$ cat /proc/acpi/processor/CPU0/power

in my /etc folder are two files of the cpuspeed.conf

/etc/cpuspeed.conf and /etc/cpuspeed.conf.rpmnew


thanks for your help

martin

The .rpmnew file is one that was created when the cpuspeed rpm was installed. Compare the two files or just mv the current one to a backup and the .rpmnew one to the active one, and see what happens.

Most rpm installations move the current .conf file to a .rpmsave one and install the .conf file the installation "thinks" you need, but some of them leave your current settings alone and put their "suggested settings" in an .rpmnew file for your edification. The later is, usually, done when there is no, or insignificant, changes from your current settings, so this suggestion will probably not help, but it's probably worth investigating, eh?

hi,

sorry but it doesn´t works

also have done yum erase cpuspeed, yum install cpuspeed

no result

but I want to understand what is going on

please tell me: if I deinstall cpuspeed and the system runs
without cpuspeed what happens in the worst case ?

what lines in the .conf files I can manipulate once more ?

martin

Without cpuspeed the system won't reduce the power (and speed) of the CPU when it doesn't need to be working hard. (E.g., while waiting for your input, etc.) This extends the life of the CPU since it will run at a lower average temperature, and reduces power consumption so, if you're running on battery power, you can work (slightly) longer before the battery runs down.

Neither of these effects are of much significance: Failure of the CPU is almost never the cause of laptop failure (mechanical damage is much more likely), and the reduction is battery life from CPU usage (and the resulting more frequent need to run the cooling fan) is almost negligible compared with the power used by the display screen and disk drives.

The .conf file should have lots of comments describing the entries you can change, and something of the effect of those changes. Look at man cpuspeed for more information.

hi,

thank you so much, yes have read the man page for cpuspeed and
I didn´t give up

after all

I tried to designed the driver for centrino/speedstep-centrino
following answers in the forum http://www.fedoraforum.org/forum/arc...p/t-19560.html

but first I did an kernel-update to kernel-2.6.20-1.2944.fc6 and now
everything works fine

this is the good answer, the more curious answer is finally I even don´t know why because this subject is not my favourite topic

thanks for your helpful answers

martin
