It has been suggested to me to move this thread from current to acpi. >From what I can tell the CPU's do not halt on idle. Top -SH from a system booted for a few hours on releng_7 or on current shows hours of time used where as releng_6 used only minutes or seconds. This is causing some sytems to overheat. I am trying to compile all the relevant information in this e-mail. If I have missed anything please let me kow. I can also provide ssh access to a developer who would like to see the problem. I see the problem on both AMD64 kernel and i386 kernel single and multi processor. Here is information I have gather so far: Is there anything else needed for the PR?
