Output of cpuinfo, cpufreq-info, lspci, modules and ioports.
Hi,
I'm running an ubuntu 10.10 on my laptop Inspiron 8600,
it doesn't scale its cpu frequency, that's "current policy" in cpufreq-info
wich is wrong:
"current policy: frequency should be within 600 MHz and 600 MHz."
the cpu is is blocked to 600 MHz and "cpufreq-set" can set anything.
I try to fix it in /etc/sysfs.conf but no way...
It doesn't work with kernel 2.6.35 but I have tested too the kernel found on:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.36-rc7-maverick/
(http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-10-16-maverick/ also)
The lastest bios was already on board and I ran a live cd
ubuntu 10.4 with 2.6.32-24 kernel and frequency scaling worked well.
In the attachment, there is cpuinfo, cpufreq-info, lspci, modules and ioports.
I hope that it will help.
Thanks.
Lionel
