           Summary: p4-clockmod gets a wrong max clock (1.2GHz insted
                    1.6GHz)
           Product: Power Management
           Version: 2.5
     KernelVersion: 2.6.25
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
        AssignedTo: cpufreq@www.linux.org.uk
        ReportedBy: andrea.cimitan@gmail.com


Latest working kernel version: I don't know
Hardware Environment: P4 1.6 GHz
Problem Description:
My p4 1.6GHz gets a wrong max speed using p4-clockmod.
Available frequencies taken from cpufreq-info (same output for cat
/sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies).

Using acpi-cpufreq:
1.20 GHz, 1.60GHz
using p4-clockmod: 
150 MHz, 300 MHz, 450 MHz, 600 MHz, 750 MHz, 900 MHz, 1.05 GHz, 1.20 GHz

I'm forced to use acpi-cpufreq :).
