FWIW:
My standard instructions for users who are asked to bisect are [1]:


<--  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]
# start next round


After at about 8 reboots, you'll have found the guilty commit
("...  is first bad commit").


More information on git bisecting:
  man git-bisect

[1] the start and end commits and the number of reboots are variable,
    but the rest of the text is generic
