1. update bios to the latest from manufacturer and check bios settings (
Must do )
Ok. I jumped on the Acer web site... The system is an APSK50 desktop. I
noticed the BIOS was from 2006 - the latest is R01-C1. I flashed that
using 'flashrom' which I found to be a lifesaver! I didn't have to get a
bootable DOS USB key etc! :D
From dmidecode:
BIOS Information
Vendor: Phoenix Technologies, LTD
Version: R01-C1
Release Date: 05/30/2007
<snip>
Handle 0x0001, DMI type 1, 27 bytes
System Information
Manufacturer: Acer
Product Name: AST690/APFH/APSK50
Version: R01-C1
Serial Number:
UUID: FEFEFEFE-FEFE-FEFE-FEFE-FEFEFEFEFEFE
Wake-up Type: Power Switch
SKU Number:
Family:
The CPU is a socket 775 PentiumD 2.8Ghz.
I reset the BIOS to optimal defaults and fired it up. No real change :(
2. restore /etc/sysconfig/cpuspeed to it's original form ( Must
as well )
Did this before I rebooted. If I don't have DRIVER=p4-clockmod set in
/etc/sysconfig/cpuspeed, when I start it I get a prompt saying that its
started the ondemand passive cooling. I assume that this means zero
frequency scaling.
This is a curious thing - when doing this manually:
# /etc/init.d/cpuspeed start
Enabling p4-clockmod driver (passive cooling only): [ OK ]
So, unloading all modules and playing manually:
# modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq
(/lib/modules/2.6.35.10-74.fc14.i686/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko):
No such device
So we can't use acpi. drat. Load p4-clockmod:
# modprobe p4-clockmod
Then lets do some tests.
# pwd
/sys/devices/system/cpu/cpu0/cpufreq
# cat scaling_available_governors
userspace performance
# modprobe cpufreq-ondemand
# cat scaling_available_governors
ondemand userspace performance
# cat scaling_governor
performance
# echo ondemand > scaling_governor
# cat scaling_governor
performance
#
Interesting. Surely this should change to the ondemand governor?!
Check if things work if they dont after bios update and orignal
cpuspeed
file and after fiddling with power savings, EIST, processor scaling,
etc.then boot with cpufreq.debug=7 and test latest kernel .35 .36 .37

Going to look into this tomorrow. It's 3:33am now on 1/Jan/2011 - so
Happy New Year to all, and lets continue the awesome achievements shown
in Fedora :)
