--Apple-Mail=_AF3457B5-41AC-49AA-8BC4-8E137E0FB62F Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii I have an old Dell 1950 that I've rescued from Linux and tossed a copy = of -STABLE on it, but am seeing a constant 0.5 load average. With the = system completely idle, and kern.eventtimer.timer=3DLACPI, the load = drops to the expected value of zero. This feels like it should be an FAQ, but short of noting that the load = is non-zero, is there a programatic way to determine if the event timer = is "broken?" The system was functioning just fine, but it always had a = constant load even when doing absolutely nothing. ?
