My laptop is a Lenovo Thinkpad X230 with an Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34). Another user also reported same problem with an Intel(R) Centrino(R) Ultimate-N 6300 AGN, REV=0x74 As a workaround, reverting patch from release 3.4.83: Johannes Berg iwlwifi: always copy first 16 bytes of commands makes it work again. Saludos, Andres Bertens PS If of any interest, here are related logs.
