Description Tomasz Ostrowski 2007-05-10 15:31:12 EDT

Description of problem:
Powernow-k8 driver does not load - it shows a message
    powernow-k8: Processor cpuid 70ff1 not supported
on my new AMD Athlon64 3800+ on AM2 connector (Family: 15 Model: 15 Stepping:
1), which does support Cool'n'Quiet. Because of this I cannot use cpufreq in my
system.

Version-Release number of selected component (if applicable):
kernel-2.6.20-1.3104.fc7.i686

How reproducible:
Always

Steps to Reproduce:
1. Boot a Fedora 7test4 Life CD on affected system
2. Watch kernel messaged

Actual results:
powernow-k8: Processor cpuid 70ff1 not supported
powernow-k8 driver not loaded and cpuspeed not working

Expected results:
powernow-k8 driver loaded and working cpuspeed

Additional info:
Additional info and proposed (trivial) patch is on Linux Kernel Bugzilla:
