Ok, I've narrowed the scope of the problem some. I moved forward
to a more recent kernel (2.6.31 to 2.6.36) and that resolved the
problem of the controller showing up as every device on the bus.
However, from 2.6.37 to the current HEAD, I have not been able to
build a kernel to run on the 460EX. I tried 2.6.37, 2.6.38, and
the HEAD and all result in the following kernel panic. I am not
sure how to proceed here. I suppose we can stick with 2.6.36 since
it works, but I'd like to understand what it might take to remedy
this.
Thanks
