@Ap. Syvertsen: Let's try to lay out everything clearly to make sure
there isn't any confusion. The swapping of the meanings of "good" and
"bad" are bound to cause confusion, so let's use the usual meanings for
any discussion with the understanding that the meanings are swapped
*only in the bisect logs.*

You said, "My linux crashes occasionally during startup with kernel
2.6.39-1 with this kernel BUG, while I'm unable to produce this on
3.0-rc1." I took that to mean 2.6.39.1 is bad, i.e. exhibits an oops
message similar to that in the bug description. And version 3.0-rc1 does
not exhibit the oops. Is that understanding correct?

It's a little problematic to bisect between 2.6.39.1 and 3.0-rc1. The
stable kernels (anything with the fourth component of the version
number, i.e. 2.6.39.y) are somewhat of a branch off of normal kernel
development, and the bisection will go more quickly if we start with
2.6.39. This version should still have the bug if 2.6.39.1 does, unless
it was fixed and then broken again, but that's unlikely. It can't hurt
to verify that 2.6.39 really does have the problem however.

So I started the bisection by marking 2.6.39 as bad (i.e. "good" in the
bisect log) and 3.0-rc1 as good (i.e. "bad" in the bisect logs). git
picked an intermediate version for testing, and that is what the
bisect000 build represents. That is correct so far as my understanding
of the situation as communicated above is correct. Does that make sense?
