           Summary: acpi_cpufreq doesn't load - Intel Q9300 CPU and shuttle
                    SG33G5
           Product: Power Management
           Version: 2.5
     KernelVersion: 2.6.25.11-97.fc9.i686
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
        AssignedTo: cpufreq at vger.kernel.org
        ReportedBy: nospamnoham at gmail.com
                CC: linux-acpi at unix-os.sc.intel.com


Latest working kernel version: none
Earliest failing kernel version: 2.6.25
Distribution: Fedora 9
Hardware Environment: Intel Core 2 Quad Q9300 CPU on a Shuttle barebones
SG33G5, DDR2 800 4GB RAM. BIOS version SG33S117.
Software Environment: FC9 updates completely running kernel
2.6.25.11-97.fc9.i686.
Problem Description: acpi_cpufreq doesn't load. Windows XP is able to do freq
scaling. CPU is can operate in 2.0 GHz and 2.5 GHz.

I checked the BIOS "PPM" option and it has "Native" and "SMM". SMM is
apparently for legacy OS. Tried both. Neither helped. 

I know that kernel.org kernel needs to be used for reporting bugs. But I'm in
the process of learning how to compile and install a customer kernel.org kernel
in Fedora 9. Will update the bug once I get that working.

Although my dmesg output shows nvidia, I have confirmed that this doesn't work
even when nvidia module is not loaded.

Steps to reproduce: modprobe acpi-cpufreq
