Default Re: Crashing when SMP enabled

Thanks for the advice, I still had the problem in 2.6.17 but I will try anyway by booting the kernel with the 'noirqbalancer' option.

I do not have the 'composite' extension in my xorg.conf file, but it seems to be somehow built-into Debian's distribution of xorg:
(II) Initializing built-in extension COMPOSITE
I've not been able to disable it, even adding the following had no effect:
Section "Extensions"
    Option      "Composite"     "Disable"
I think I may have to recompile xorg myself to disable the extension.

I also realised that I have not yet tried disabling TwinView so when I am ready to restart for another test, I will do that at the same time. If I can get either the 'nv' or 'nvidia' driver to work with TwinView disabled I can be more sure that the problem lies with the 'nvidia' driver and not the kernel or hardware.
