--- Comment #49 from Srivatsa S. Bhat <srivatsa@mit.edu> ---

By the way, another approach I have in mind is to remove the usage of
work_on_cpu() from the powernow-k8 driver (since that's the only noticeably
different thing about this driver), and check if it solves the problem. That
way, powernow-k8 would become mostly similar to all other cpufreq drivers and
this might make it easier to isolate the issue.  (Of course work_on_cpu() must
be remove with care, such that the correctness of the code is still
maintained).

Regards,
Srivatsa S. Bhat
