Intel Atom N550 not recognised

Hi,

i buy mainboard Jetway JNC9C-550-LF with Intel Atom N550. I installed Archlinux x86_64 with newest kernel 2.6.36.3 and i will use cpufrequtils to settings frequency on processor, but when I try cpufreq-info, console give me:

cpufreq-info no or unknown cpufreq driver is active on this CPU

and "modprobe acpi-cpufreq" give me: "No such device..."
Is any solution for me?

Sorry for my bad english

PS: i try this on kernel 2.6.37 from Testing and kernel-lts from Core with same result.

grub line: acpi_osi=Linux
module: eeepc-laptop

Try and return with results.

I add grub line "acpi_osi=Linux" and try modprobe eeepc-laptop with the same results (modprobe output is "No such device"). I try this on LTS kernel and on 2.6.37.

Do you have the 'acpi' package installed from [extra]

SOLVED: Jetway have on site new BIOS for my mainboard. This BIOS add CPU Microcode and now cpufreq-info write correct informations and "modprobe acpi-cpufreq" works..

Thanks guys.

Uh good to know BIOS can still be an issue. Haven't had problems of this kind for years.

Another option for in case there is no BIOS available is to use the microcode_ctl package which updates the CPU firmware on-the-fly.

pacman -S microcode-ctl
