@ Carey Underwood
This may have turned into a hodgepodge but, in my opinion as a non-techy, there is something fundamentally wrong for so many people to be having similar issues. I've had to turn off multiple cpu support to get 100% stability which is not a satisfactory solution. It may help if someone could suggest to all affected some form of test (or tests) which may be useful in trying to pin down what is causing the problem; a problem that only seems to have surfaced with Jaunty. My, and many others systems, were perfectly stable with Hardy and Intrepid.

As a matter of interest, the latest official kernel upgrade to 2.6.28-15-generic and nVidia 180.44 seems to have brought better stability. I can now use both cpu cores without the system freezing every 20 minutes although the occasional freeze still happens.
