Reverting commit 1ff6e97f1d993dff2f9b6f4a9173687370660232 ([CPUFREQ] cpumask: avoid playing with cpus_allowed in powernow-k8.c) removes the warning.

Ok. One small correction. The computer seems to enter S3 correctly. So the suspend to ram works. BUT the resume from ram seems to get stuck somewhere.

Patch in http://lkml.org/lkml/2009/7/7/43 fixes the STR problem for me. I don't care about the warning. Feel free to close this bug.
