Hey James,
I'm a bit confused as to the purpose of your thread. I wasn't attempting
to answer your question just point to information showing that AMDs and
Intel processors varied. I have no idea about your technical background,
so I can't address the issues you raise and I'm not much for getting
into a right/wrong question/answer session attempting to guess if you're
attempting to question my background or whatever.
I'm also not sure your link above does much for you original question.
It points to something I don't know what. A friend of mine runs the red
Hat desktop team and he has mentioned the work they do on different
processors several times.
I do know that when we built a 2.6.8 kernel for Sun's JDS Linux it
panicked on AMDs so we had to compile it in i386 mode. Of course that
kernel has lots and lots of SUSE patches and we were using their
sources. Perhaps you are correct about the source from kernel.org - but
that's not what we have here. We have Ubuntu packages made for AMDs and
Pentiums. I don't know that it matters if an i686 package in source will
compile on an AMD or not. The developers of this distribution have
supplied packages for us and they are very specific as to what
processors they support.
That's what the mailing list needs to know.
