Go fix your userspace to n= ot > not run when not needed. Hi Peter! This was already mentioned in one of these threads.=20 The summary is: The device this kernel is running on dosn't want to (or can) rely on userspace to save power. This is because it is an open system, without an app-store or the like. Everyone can run what he wants. So anything relying on (all) userspace solves a different problem.
