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
