Public bug reported:
After installing powernap on a Ubuntu 11.10 Server system, and possibly
only after a subsequent reboot, I found the system to be running with
the "performance" scaling_governor, which was a change from the original
behaviour where the system would have the "ondemand" governor by
default.
Resetting the scaling_governor to "ondemand", either via calling
/etc/init.d/ondemand or by manually echoing the setting into
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor, was temporarily
succesful, but after about a minute the scaling_governor would again be
found set to "performance".
I believe the problem may be in /etc/pm/power.d/cpu_frequency, which
doesn't seem to know about /etc/init.d/ondemand, but I'm afraid I don't
know enough about upstart et al to suggest a good fix.
Thanks for powernap, and thanks for reading!
