As I said, bisecting does not work if you can't build the kernel because 
of un-defined symbols spanning most of the revisions you are interested

I have isolated the revisions that do not build so I should be able to

be able to investigate the original issue.

If it were practical to do a build test on all supported platforms before 
submitting patches then this would not be so much of an issue but ...
