    If I boot up on 2.6.20-git10 and run "git bisect bad", "git bisect good
    v2.6.20-git10" or "git bisect bad v2.6.20-git11", it says it's not a git

    I am still no clearer what's required. If I do "cg-clone" I get
    2.6.21-rc5. The previous one got me 2.6.21-rc4.
    The manpages and the tutorials I've looked at are quite cryptic and the
    commands do not produce the expected results.
    As indicated above, I followed the instructions bullet by bullet without
    any clear understanding of the tools.
    1) Ran the commands as above,cg-clone; git start; git bisect bad
    <checksum>;git bisect good <checksum of 2.6.20-git10 > I presume.
    2) 2.6.20-git10 is the last good kernel.
    3) 2.6.20-git11 and later are all bad.
    4) I do cg-clone which gives a kernel whose Makefile is 2.6.21-rc4 (or
    whatever is current).
    5) I get a kernel named 2.6.20-g208367e after make - rebooted and it
    fails the same way as 2.6.20-git11.
    6) ran "git bisect bad".
