When using a kernel that has smp support enabled the computer will randomly power down. It does not happen when using a non-smp kernel. There is also no problem when using M$ with this chip set. There are no error messages. It just shuts down. Because of this I'm unable to make full use of my dual core. Which of course sucks. ;-) I attached a copy of my dmesg so you can see what hardware I'm using. I'm using ide hard drives cause I'm too broke to buy up to date sata drives. I lost one of my drives because of the power downs. So now I'm broke with one less drive. :-( Below is a request for help I sent to the board manufacturer. It's worthless to you except for the mother board information. Can you help?

You may contact Nvidia for the more information on the compatibility issue on the Nvidia chipset and your version of the Linux. Benny Acosta Posted : GMT 2007/07/21 19:27:24 If the linux kernel is compiled with symmetric multiprocessing support, the computer will power down at random intervals. It runs quite well otherwise. But the problem with powering down means that I am unable to make full use of the dual core processor. If only one processor is being used ( non smp kernel), the mother board is fine. No power downs. With no error messages to reference, I have no way of knowing why the system would power down. It does not do this with windows. Is there some kind of patch available that would allow me to run a linux smp kernel. I don't want to replace my motherboard.
