I have no idea if this would be of help but I am hoping that it may just 
provide the clue to the problem.

Over the past 2 days I have been compiling a couple of my own versions 
of the 2.6.32 kernel now used in 10.04.

One of the things which I noticed - quite by accident during the ~2.5 
hours it takes to compile it on my system - is that when the compilation 
came to the nouveau driver a warning message scrolled by with something 
like, "NV40 graph_int 1188 bytes is greater than 1024 bytes..".

Similar warning messages appear throughout the compilation. I did catch 
another one which showed along the lines of "main usb 1868 bytes is 
greater than 1024 bytes".

Now, what I did not expect is to have warning messages, and similar 
comments about incorrect pointers and indexes, showing up during the 
compilation of the installed kernel in Lucid 10.04.

The kernels compiled and ran/run OK [with qualification, explanation for 
another time] but I am now wondering if the kernel in Lucid is kosher. I 
have compiled kernels before, in a different distro, and never struck 
such warnings/messages before.
