This is the procedure I followed.
<--  snip  -->

# install git and cogito on your computer

# clone Linus' tree:
cg-clone  
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

# start bisecting:
cd linux-2.6
git bisect start
git bisect bad 86a71dbd3e81e8870d0f0e56b87875f57e58222b
git bisect good ac98695d6c1508b724f246f38ce57fb4e3cec356

# start round
cp /path/to/.config .
make oldconfig
make
# install kernel, check whether it's good or bad, then:
git bisect [bad|good]
========================================================
I built and installed the kernel downloaded using "cg-clone", booted it 
up  and ran "git bisect bad".  I'm also somewhat confused as the first 
failing kernel is 2.6.20-git11, the Makefile says the kernel got with 
cg-clone is actually 2.6.21-rc4 and it built as  2.6.20-g208367ee.

Sid.
