--- Comment #13 from Peter Weber <bugs at ttyhoney.com> ---
Hello!
As far as it looks I'm using CONFIG_CPU_IDLE_GOV_MENU=y since some months and
it seems to work without regressions. These are my options:

#
# CPU Idle
#
CONFIG_CPU_IDLE=y
# CONFIG_CPU_IDLE_MULTIPLE_DRIVERS is not set
CONFIG_CPU_IDLE_GOV_LADDER=y
CONFIG_CPU_IDLE_GOV_MENU=y
# CONFIG_ARCH_NEEDS_CPU_IDLE_COUPLED is not set
CONFIG_INTEL_IDLE=y

Nonetheless I have to note, that currently - as time of writing and not in the
past months - the results of the benchmarks are varying. I assume this is
caused by the steadly changing releases of "xf86-video-intel-2.99.***-*". You
can close this bug or resolve it, if you want. I don't know what I have to
select ;-)
