To save the power kernel tries to group different timer events together to reduce number of CPU wake= ups from idle state. The problem is that load average accounting also based on timer events, and if system is idle, each time it fires, there is often something else to do, that is getting accounted into load average. --=20 You are receiving this mail because: You are the assignee for the bug.=
