[ltp] Power consumption 2.6.22-hrt1 vs. 2.6.23-hrt1

[Nils]

Hi,

has anybody observe a higher power conumption with 2.6.23-hrt1 ?
With powertop I see much more interrupt events and the following proccessor 
states:

C0 1%
C1 0%
C2 50%
C3 0%
C4 50%

With 2.6.22-hrt1: (same configuration and hardware)

C0 1%
C1 0%
C2 2%
C3 0%
C4 97%


=> I need ~2 Watt more power with 2.6.23-hrt1.

Any idea?
