cpufreq broken in 2.6.15-rc5

Hi,
I'm using the ondemand governor with powernow-k8 on an Athlon 64 3200+
desktop. However, it's acting a bit strange:
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
2000000
# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
2000000
This results in the processor always running at 100%.
The relevant part from dmesg:
powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.50.4)
powernow-k8: 0 : fid 0x0 (800 MHz), vid 0xa (1300 mV)
powernow-k8: 1 : fid 0xa (1800 MHz), vid 0x6 (1400 mV)
powernow-k8: 2 : fid 0xc (2000 MHz), vid 0x2 (1500 mV)
cpu_init done, current fid 0xc, vid 0x2
My .config:
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
CONFIG_CPU_FREQ_STAT=y
CONFIG_CPU_FREQ_STAT_DETAILS=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y
# CONFIG_CPU_FREQ_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_GOV_POWERSAVE is not set
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_GOV_CONSERVATIVE is not set
I haven't tried any earlier rc's, but it works with 2.6.14. I'd be happy
to answer any questions.
Thanks,
Mark
