Hi!

With 3.10-rc2 periods of basically on an ThinkPad hyperthreading
I am using full hz:

martin@merkaba:~/Linux CONFIG_NO_HZ_COMMON=y
# CONFIG_NO_HZ_IDLE is not set
CONFIG_NO_HZ_FULL=y
CONFIG_NO_HZ_FULL_ALL=y
CONFIG_NO_HZ=y
CONFIG_RCU_FAST_NO_HZ=y

And P-State driver
Kernel config

It seems the powertop is correct. I saw that kernel getting work seem bogus to,
