Can you list the properties of the idle states in this configuration, that is:

$ grep -r '.*' /sys/devices/system/cpu/cpu0/cpuidle/state1/

and analogously for state2 and state3, and send the output of this?

On my desktop system the above comment produces the following output:

/sys/devices/system/cpu/cpu0/cpuidle/state1/disable:0
/sys/devices/system/cpu/cpu0/cpuidle/state1/above:1022634

Thanks!
