I noticed a significant increase going from 3.0 to 3.12 . I have at least identified one big difference: DDR is no longer tri-stated, which accounts for some of the difference. I use 'echo mem > /sys/power/state' for my test case. Do you know if someone is looking into this issue, or if there are pending patches somewhere? Best regards, Bj?rn Erik Nilsen
