Hi all
I cannot use cpufreq on an ACER Extensa 5220 laptop with a Celeron 550 @
2GHz CPU. Reading various posts and articles, I saw that some kernel
versions have been able to use acpi-cpufreq on these CPUs and some cannot.
Currently using 2.6.26. acpidump output, cpuinfo, dmesg, lspci are at
http://home.arcor.de/g.liakhovetski/extensa5220/. Is there any chance to
get cpufreq fixed on this system?
Thanks
Guennadi

Celerons don't support speedstep. So, no.

Indeed, I was confused by the contradictory articles I found on the Net:-(
Looks like only Allendale-512 supports speedstep.
