[Bug 717454] Power consumption of 3.0.4 kernel is 10-20W higher than 2.6.37 on new i7 based SandyBridge processors

--- Comment #10 from Richard Brown <rdb@xxxxxxxxx> 2011-09-17 19:58:27 UTC ---
Situation is identical on my Gulftown (i7 980x) workstation

CPU when idle is spending most of its time in C4 state (99-101% according to
powertop) but power consumption is still 6-10W higher with kernel 3.0 compared
to 2.6
