1) cd to wherever you have your kernel checked out

2) `git bisect start`

3) if you're already on a known-bad commit, then mark it as such:

  `git bisect bad`

4) Mark the last known good commit as such:

  `git bisect good <commit / tag>`

git bisect will choose a commit to test.

5) Build, install and boot your kernel as you usually do

6) Run whatever test you need to determine if the booted kernel is good or bad
(check dmesg in this case)

7) Mark the commit as good or bad. Git will choose another commit for you.

8) Goto 5.

`git help bisect` will give you more information.

At the end of the process git will tell you the first bad commit found.  You can
dump the bisection log with:

`git bisect log`

which you can reply here with.

HTH.

Cheers,


Brett
