I've noticed on several of my laptops that they run way hotter with freebsd than other systems (linux, windows). Most are newer models that have either acpi issues or lack speedstep support. But I suspect there's something else going on in the basic system. I find it hard to believe the clock rate is the cause of this extra work but haven't dug into it (I hoped judicious use of hwpmc would pinpoint what's going on). Sam
