But now that SMP mode doesnt slow down my internet connection I am more or less fine. The little wiggle left is tolerable for the time being. The only thing I could think of is that the motherboard with the second cpu not being used gets a voltage spike (or other uncleanliness) and that is affecting the video card. Or perhaps the 40 degrees cooler the thing runs without the second cpu makes the video card unhappy :) steve > > I can't imagine how the display problems could be related to > the kernel.
