    I found a new one in -rc3 vs. -rc2.
    Only one of my cpus seems to powered down by cpufreq, because the
    topology gets filled out wrong:

    correct with -rc2:
    #grep . /sys/devices/system/cpu/cpu*/cpufreq/affected_cpus
    /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus:0 1
    /sys/devices/system/cpu/cpu1/cpufreq/affected_cpus:0 1
    /sys/devices/system/cpu/cpu2/cpufreq/affected_cpus:2 3
    /sys/devices/system/cpu/cpu3/cpufreq/affected_cpus:2 3
    (The system has 2 dual core Opterons)

    wrong with -rc3:
    #grep . /sys/devices/system/cpu/cpu*/cpufreq/affected_cpus
    /sys/devices/system/cpu/cpu0/cpufreq/affected_cpus:0 1
    /sys/devices/system/cpu/cpu1/cpufreq/affected_cpus:0 1
    /sys/devices/system/cpu/cpu2/cpufreq/affected_cpus:0 1
    /sys/devices/system/cpu/cpu3/cpufreq/affected_cpus:0 1

    I bisected this bug down to these commits:
    > Mark Langsdorf (2):
    > [CPUFREQ][1/2] whitespace fix for powernow-k8
    > [CPUFREQ][2/2] preregister support for powernow-k8

    HTH
