I just tried applying patch against 2.6.11.8, well it builds fine, however
when I try to use it (Athlon64 3200+ s939) I get:
powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.40.0)
powernow-k8: 0 : fid 0x2 (1000 MHz), vid 0x12 (1100 mV)
powernow-k8: 1 : fid 0xa (1800 MHz), vid 0x8 (1350 mV)
powernow-k8: 2 : fid 0xc (2000 MHz), vid 0x6 (1400 mV)
Losing some ticks... checking if CPU frequency changed.
cpu_init done, current fid 0xc, vid 0x6
which looks quite fine, but after ondemand govenor is started:
