Comment 33 for bug 272247

The only thing that I can see here is that you typed kernel versions number instead of revision number (which is a "pure" number without dot, like 100644) :

git bisect bad 2.6.27-3
fatal: Needed a single revision
Bad rev input: 2.6.27-3

Actually, we know that the bug was already there with 2.6.26 and 2.6.27 kernels, however 2.6.24 kernel does not have this bug, so you should test kernel revisions between 2.6.24 and 2.6.26. Since there are thousands revisions between each release, there is probably a way to "jump" between revisions easily so you can quickly identify which one is the faulty one.
