    Fun, so that kernel actually works but the one I am building from
    wireless-testing.git does not. The curious thing is it doesn't boot
    even if I remove my 802.11 module... so something is fishy. This is
    likely a config issue. After booting with the above kernel though I
    generated a new one with

    make localmodconfig

    and then enabled my 802.11 modules. Still, no luck.. Going to reset my
    tree, I had manually merged Linus' latest stuff in but I don't think
    this should matter.
