Yeah, I think this patch will be helpful, but we need some testing. Do we have
launchpad bug tracker of this bug? Ogra and Lee, are you guys aware of this bug?
I am not playing with the Maverick rootfs.

Rob, thanks for fixing this. But we need know more information about the
original patches and the status of this patch? Will this patch in mainline or in
the OMAP4 upstream queue? That will be much easier for us to review.
