Re: [2.6.0-test7] cpufreq longhaul trouble

[Jurgen Kramer]

Some more details. Although this is an 800MHz CPU
/sys/devices/system/cpu/cpu0/cpufreq gives:

[root@paradox cpufreq]# more *
::::::::::::::
cpuinfo_max_freq
::::::::::::::

I can overclock my machine to 995MHz..;-) Setting scaling_setspeed
doesn't seem to do anything.

Cheers,
