Summary: cpufreq scaling not available (Sumicom S635F, 945GM,
PhoenixAward 6.00, CoreDuo L2400)
Product: ACPI
Version: 2.5
KernelVersion: 2.6.*
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: BIOS
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
CC: [EMAIL PROTECTED]
Most recent kernel where this bug did not occur:Always
Distribution:Gentoo (2007.0, gentoo-2.6.20-r8)
Hardware Environment:Sumicom S635F, 945GM/ICH7M, CoreDuo L2400
Software Environment: Gentoo Linux, Bios PhoenixAward 6.00
Problem Description: Cannot register cpufreq driver
How can I add attachments to this message?
Unfortunately I can't check whether frequency scaling is working on Windows.
There's no Windows at hand. If somebody points me to a windows tool I can
run under wine, I will do so.
Same result with kernel versions 2.6.19, 2.6.20, 2.6.21, 2.6.22
Same result with compiled in or module cpufreq drivers, tried
all reasonable combinations of kernel options, patched sources
with linux-phc as described at forums.gentoo: No luck.
Built kernel with:
[*] ACPI Support
[*] Procfs interface (deprecated) (NEW)
<*> AC Adapter
<*> Button
<*> Processor
<*> Thermal Zone
[*] Debug Statements
[*] CPU Frequency scaling
[*] Enable CPUfreq debugging
<*> CPU frequency translation statistics
Default CPUFreq governor (userspace) --->
<*> 'performance' governor
<*> 'powersave' governor
--- 'userspace' governor for userspace frequency scaling
<*> 'ondemand' cpufreq policy governor
<*> 'conservative' cpufreq governor
--- CPUFreq processor drivers
<M> ACPI Processor P-States driver
<M> Intel Enhanced SpeedStep
[(*)] Use ACPI tables to decode valid frequency/voltage
(deprecated)
--- Built-in tables for Banias CPUs
<M> Intel Speedstep on ICH-M chipsets (ioport interface)
--- shared options
[(*)] /proc/acpi/processor/../performance interface (deprecated)
[(*)] Relaxed speedstep capability checks
(*) means: Tried with and without.

Ok, I'll stop it here. Hope to learn how attachments are used.
Result of iasl and acpidump will follow.
