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:
