    Thank You git bisect has proven to be incredibly interesting.

    One question/problem - maybe an incomplete understanding of git.
   
    What I need to do is get to some version of 2.6.16 - as they all
work for me.

    cut in my patches.

    And THEN start bisecting while retaining my patches.

    Is that going to work or am I going to have to repatch each time ?

    Basically can I use git to insert a patch into the middle of its
delta history and then advance forward from there ?

    It is rapidly becoming obvious that competence with git could have
big payback.
