Package: powernowd
Version: 0.97-1
Severity: normal
Hi,
I installed powernowd and added the following modules to /etc/modules
to make it work:
powernow-k8
cpufreq-userspace
On startup, powernow-k8 detects the cpu's:
powernow-k8: Found 4 AMD Athlon 64 / Opteron processors (version 1.60.2)
powernow-k8: 0 : fid 0x12 (2600 MHz), vid 0x8 (1350 mV)

powernow-k8: 4 : fid 0xa (1800 MHz), vid 0x10 (1150 mV)

When I check /proc/cpuinfo it seems powernowd has only scaled down the first core
of each processor:

The first core of each processor gets clocked down to 1800Mhz, but the
second cores remain at 2600Mhz.
I've tried this both with the 2.6.16 and 2.6.17 Debian kernels.
Greetings,
Rik
