You can ignore the alignment warning, it's been decided that Intel driver/firmware/hw will not work properly on platforms that cannot do unaligned loads efficiently. I've tried sending a patch to add CONFIG_HAVE_EFFICIENT_ALIGNED_ACCESS or something like that so that we can fix it up if that is unset or make the driver depend on it, but it hasn't stuck so far, so for now, ignore the warning and don't try to use Intel wireless hw on platforms that don't like unaligned loads. johannes --=-W3QWfvFM0t4eunBFSZ+r Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Comment: Johannes Berg (powerbook) iQIcBAABAgAGBQJJDqdJAAoJEKVg1VMiehFYMZUQAIcPpIekA/pqFbC+9oaeq6uB LIWzRm1BuozroPS+nIQov15HnSdXUGWjA/q0aNhjGGcgiIRznQo6qo3TdAf/JJtn dXlqldT3XkwsxxVE/TdMBH+augyyd5I1rhNhWtmV3GpMwN+m7iaba/mFmL8Ny2tk CPCxc/8rmmClHOk/BJfPUK8hvuPXALYKzE+KSmPyFndJPUK4pg9h/OlLxmKJjUAp AhI9DRQ4Ysr3E/ZI88r9PpZJI00m2C0mXRMnxugAS5T/DpdoZObc9aquKawcOWpF Spvz/5sM/hXgKJDm7n1Ej3AprfedASMr4XReKcGPvIr37KxFoV4/KmkRpSMDO4hM 6ipQnek+OMDUE76PIZbZrmeTPySjYs+JaHRnua4j5nlGrbGNwEBQCZRXlak3bMLj 1xe/vmfWTYpSTDyZ0ECGTXwtgtTnscFMlrB2T2hlfXCn3kY3LhpbD7D+95cqyKFD HPw30RBLFCW7ZKm+YEy7iowpyXoYckH1HtL1/iEDWYmCA8b6mLVEtVQa6lcEj4Sj vKr4Pj1f8i41nFaWLrjPszB0yWbeFz6R0T0f9WsSBQHcKwf3TI7LcCawefOed1qs td+3HLtGYhr2JaYMKGrpDmS/hcFWY4Lg8ZPaC3YMkEBwRM4Mqo6IFJsyDCHtYMC+ J+27fLwDqsTHGvm7Mo1f =lwAS -----END PGP SIGNATURE----- --=-W3QWfvFM0t4eunBFSZ+r--
