           Summary: p4_clockmod unusable with ondemand even by manual
                    choice
           Product: Power Management
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: cpufreq
        AssignedTo: cpufreq@xxxxxxxxxxxxxxx
        ReportedBy: nemesis@xxxxxxxxxxxx
        Regression: No


The following patch:
[CPUFREQ] Prevent p4-clockmod from auto-binding to the ondemand governor

certainly seems like a good idea.  No reason to use an inefficient governor by
default.  However, as a side effect, setting the transition latency to this
value makes it impossible for the user to _choose_ to use ondemand even when it
is the best choice for his environment.  On a Celeron-M processor, ondemand is
useful for reducing heat output and keeping the fan from turning on all the
time, and p4_clockmod is the only module that works for such processors.  Until
2.6.29 this was a very useful thing.
