Hmm, ok, that points to something else maybe... Now I wish I had my ftrace-mac80211 patch ready. Well, the patch is almost ready but we can't use ftrace in modules yet... Maybe there's some timing issue. I still think it's iwlwifi getting confused about what mac80211 is telling it as described, but it seems it's a little more subtle than what I said. johannes --=-jyAFasi1fRzbswS7bB4X Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJKAu30AAoJEODzc/N7+QmaYJkQAMQdPR+ggoQAFKJskQrQnKjU SydA8uLXNTkkJ+/SAKfZQrGmvz6r2dz2bN3SdM3sTjkGlWDC9YOkhik+5CqRhoSy DpM9WOHuE8aSR361It0Gub2jEnfq5NoOFvJE3+trDHU43wpu7x32Vufg2BBgAO2b sLpRXqeRpqKbotofTWt4cpekIvGeJxCRfpOzMNpvytOQtLIXDvZpwTIFcWkDgHoM 79C0lMpdB5G/Lch9s+eSGDVmQgayq1K73GzEFgjENBUPm6910wXFp2vafIRM6iIJ Z7u2KmLaMj/5wrtIbbvWJ8CevrOE9zK3tO5VNct7vM1GTgvIQ2+Mq0ncPxVzquqL Bj2Dh+pSnlIOzHHh74r5A1k/g8Wuz1IHOdK1DlFCjpxbv9Ytq3c5mRV8t6Wh4XHc jAkzYI2sz0r8R9z0zDG6jljro2+tBKxfA2f4Sz5m+B5o3UAhz4kHTX4bxtgU7dC3 Pk89b2GHycKgmtchJ04sM1lqNlSIXGLMtqk8L5eJtTVSgdX5yfrkmeljmp8b1mJU CC8IdBQtqhej1T4l2Ok8RZWV4EE8FpuL+FaZAeeLOOGfes+potw3S11RkHLp3oIW ZTRYn0D+4v/7mchQcZ3J0InTw0j3UHrPuYkqSh3ENoAQFdCk/zyqRErxvh2MASPS 8BVH+hjWIgvXTA3RqQ8X =RbgZ -----END PGP SIGNATURE----- --=-jyAFasi1fRzbswS7bB4X--
