Hi Mathieu,
Thank your for reporting bugs and trying to make PowerNap and Ubuntu
Server better.
I have looked into this and in fact this is not an issue with PowerNap
directly, but rather with acpi-support/ondemand init scripts.
1. When the machine boots up, then it executes the acpi-support init script
2. This init scripts, also executes the /etc/acpi/power.sh script.
3. Then, the power.sh script, executes pm-powersave (which cases all the
scripts installed by powernap to be executing during boot time)
4. Way after this is done, the /etc/init.d/ondemand init script sets the
CPUFREQ to ondemand.
This mean that the ondemand frequency is set to ondemand way after pm-
powersave has been executed, causing the cpu_frequency script to save
the "incorrect" governor.
Thank you for pointing this out. Your patch looks good. I'm merging it.
Cheers,
