    It's also godsend for users who want a regression they observe fixed.

    If you can tell which patch broke it you often turned a very hard to
    debug problem into a relatively easy fixable problem.

    As an example, [1] was an issue a normal user could discover, and
    bisecting made the difference between "nearly undebuggable" and
    "easily fixable by revertng a commit".

    As already said in thread, the required instructions for bisecting are
    relatively short and simple (assuming the user can build his own
    kernels).

    Not everyone has a slow connection.

    For me, the speed of cloning a tree from git.kernel.org is completely
    cpu bound and limited by the speed of the 1.8 Ghz Athlon in my
    computer...

    But if there is a real life problem like people with extremely slow and
    expensive internet connections not being able to bisect bugs these
    problems should be named and fixed (e.g. by sending CDs).
