Cebulski My previous dreaming post reminded me on an interesting article I read in the New York Times magazine last week about the science of sleep. It's an informative piece that examines everything from the history of sleep to cultural views on getting ZZZs to medications to mattresses. You can check it out online

Hi!Okay so the problem seems to be we are using unreliable lapictimer.. which is stopped in C3 (and in C2 on broken machines). I do not see any mechanism to disable lapic; there seems to be somemechanism to work around stopped lapic timer is used (inacpi/processor_idle c) but it does not seem to bring home the bacon.

So this break it’s desire I finally stopped doing stuff desire enough for my body to let me know I’m exhausted. I came domiciliate & slept & slept & slept. I woke up worked for a client slept. Did some bookkeeping for another client. & slept. For a while I thought I was depressed but really I evaluate I was just tired. & It’s been great. But tomorrow I’m off to Andover again. & then I don’t really get to stop until I’m in Wisconsin (if then). This entry was postedon Sunday. November 25th. 2007 at 12:41 pmand is filed under.

My Macbook pro be to wake from sleep by itself. I have turned off the "change state by Bluetooth" and have no usb peripherals connected. I called Apple and they have no ideas. Any similar problems or ideas?Thanks in advance. There was an item on MacFixIt recently about this. I don't think they had a solution but were noting that they'd had several reports of the problem.
