Hello everyone!
Sorry for being so OT (again). I had to recompile my own kernel and now
cpufreqd doesn't work. I wonder what I need to enable in the kernel to have
cpufreqd work? What should be the standard cpu frequency scheduler? Which
other schedulers can or must be there? Can I put them into the kernel or will
they have to be modules?
My current kernel config can be found as:

Thanks for reading so far and thanks in advance even more for thinking about
it.
Kind regards
Julien
As I've written to your PM off-list before.
If this is, like it is ...
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_TABLE=y
# CONFIG_CPU_FREQ_DEBUG is not set
# CONFIG_CPU_FREQ_STAT is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
... and it is, just run
cpufreq-selector -g performance
when you're making music and run
cpufreq-selector -g ondemand
for office thingies etc.
and don't forget, you might need to push Ctrl + C, if the terminal
should hang.
Don't call this issue OT! It is a PITA and not OT.
