yet another cpufreq problem.

have a vostro1400:

in the past frequency scaling works fine, but now only works with one core:

Did you check whether acpi-cpufreq has been loaded effectively or not?

Cypher · 2008-12-11 03:00:21

[root@SDF2 rudolph]# lsmod | grep cpu
acpi_cpufreq            9228  1
cpufreq_stats           6916  0

cpufreq_ondemand        8588  0

looks like is loaded.

So one core does not seem to initialise correctly. Is this after suspending to RAM/disk? Did you check dmesg? Does the problem persist after a reboot?

Cypher · 2008-12-11 03:14:08

now im upgrading arch, when finish check if works after suspend.

Cypher · 2008-12-11 03:32:58

yeah, after suspend dont works, how can solve this ???

Try this:
