Problem: AMD X2 powernow-k8

brandon · 2009-03-09 21:49:39

modprobe powernow-k8 gives :
"FATAL: Error inserting powernow_k8 (/lib/modules/2.6.27-9-generic/kernel/arch/x86/kernel/cpu/cpufreq/powernow-k8.ko): No such device"

(time stood still on the iron hill)
cpu in question : amd x2 4800+ brisbane
mobo in question : asrock A780FullDisplayPort

in bios : am2 boost - disabled
cool&quit - enabled
enhanced halt state - enabled

i tried all bios combinations, and nothing wields a victory.

i saw few people had the same problem, and had the same dmesg msg,
"powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ processors (2 cpu cores) (version 2.20.00)
powernow-k8: ACPI Processor support is required for SMP systems but is absent. Please load the ACPI Processor module before starting this driver.
powernow-k8: ACPI Processor support is required for SMP systems but is absent. Please load the ACPI Processor module before starting this driver.
"

if anyone has any ideas or hints, i'd be more than glad to listen.

thnx in advance!

Tried "modprobe processor"?

brandon · 2009-03-10 07:04:30

tried. but like holy water, did no harm, nor it helped in any way. error msg is still there

try loading freq_table (and processor) first, because powernow_k8 depends on both. I have the same cpu you have and i have no problems loading the powernowd deamon.

That's not an Arch kernel, that's for sure. Why don't you ask on the Ubuntu forums? Looks too similar to an Ubuntu kernel to be anything else. We're not a 'general Linux dump' forum.

Or be clear and concise about your problem. Are you running an Ubuntu kernel on an Arch installation (proof if you claim so).

brandon · 2009-03-10 20:37:49

@B, it was pure arch.

Anyway, reinstalled the system, and got a new flashy msg
"MP systems not supported by PSB BIOS structure" , and that seems like a dead end.

Found some guys tutorial http://wejp.k.vu/projects/howto_cnq_athlon_64_x2/
but that potential solution seems kinda strange/risky to me.

*edit, updated system via pacman -Syu, and now when tried modprobe powernow-k8 i get the same error msg like in the first post "ACPI Processor support is re..."

Hi i have an AMD X2 4400++ at home and no problems with cpu scaling with the powernow one or acpi-cpufreq . Will look at home if i can modprobe the module, post the modules i use

trotos · 2009-07-28 08:51:48

bump

anyone. This is realy frustating

And i have got cpufreq working , i just modprobed powernow-k8 and changed the cpufreq config file

Take a look at your pacnew errors and fix them

Also make sure that in your BIOS cpu scaling is enabled

@brandon
I don't know if using a custom DSDT is dangerous but there are some (scarce) references to its use on the net.
The objective is always to go around some bios bug, I have looked into this in the past and what I could understand is:

1) it is not easy because not many people know exactly what they are doing (you will be looking at decompiled code, not pretty source code) so if there are errors later on they just try to skip/omit the small bit of code that is causing trouble, and not many people actually resort to using a custom DSDT (there aren't many guides or information out there that I could find when I looked into it).

2) you may run into errors/warning when trying to compile your custom/modified DSDT with the intel compiler because your bios acpi code may have been originally compiled with the MS compiler, which is a lot more permissive (read, doesn't strictly follow the standards). This causes the intel compiler to at best throw warnings or fail to compile because of errors and that leads you to 1) (the author of the page you saw mentions this briefly)

But give it a go anyway, if it is important for you to have cpu scaling take a good look at it and try.

trotos · 2009-08-27 12:13:43

ok how do I completely remove everything that has to do with the cpu, rebuild the kernel and reinstall the cpufreq???

I'vew tryed anything and there must be something with the kernel.

Or is there a utility to check out the kernel paramerts?

and how do I set the amdX2 +4600 correct options? s939
