You need to be on a branch. If git-branch says this:

$ git branch
* (no branch)

then git will not allow you to bisect:

$ git bisect start v2.6.24 v2.6.25
fatal: ref HEAD is not a symbolic ref
Bad HEAD - I need a symbolic ref

Try first checkout out a new branch:

$ git checkout -b bisect
Switched to a new branch "bisect"

$ git bisect start v2.6.24 v2.6.25
Switched to branch "master"

Good luck!
