Hmm, I know. However, in my case, this is not possible as I keep a
number of patches I'm actively working on on top of the history by
rebasing my git tree constantly. And without these patches, the platform
won't boot, so bisect will almost certainly come up with an unbootable
image. But that's just a sidenote :)

I was wrong with the range I provided. The change came in after -rc5,
and I found 57921c31 ("libertas: Read buffer overflow") to be the
culprit. Reverting it brings my libertas device back to life. I copied
the author.

Thanks,
