[Bug 111375] No powernow support on Athlon 64 3800+

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Binary package hint: powernowd

I can't get powernowd to work -- can't even insert the kernel module:
# modprobe powernow-k8
FATAL: Error inserting powernow_k8 (/lib/modules/2.6.15-28-amd64-server/kernel/arch/x86_64/kernel/cpufreq/powernow-k8.ko): No such device

Here's the tail of /var/log/messages:
Apr 30 20:23:37 beavis2 kernel: [ 7780.188893] powernow-k8: Processor cpuid 70ff1 not supported

# uname -a:
Linux beavis2 2.6.15-28-amd64-server #1 SMP Tue Mar 13 21:03:51 UTC 2007 x86_64 GNU/Linux

As per a similar old bug, I'm running sh -x /usr/share/powernowd/cpufreq-detect.sh:
