I'm a little confused at what I am seeing below.
Normally what happens is that after a kernel compile and test. You call
"git-bisect bad" or "git-bisect good" and then git-bisect picks the next
kernel to test. Then you compile and test that one. It looks like
you called git-bisect bad several times in a row without testing....
