Forwarding original message to make sure it isn't lost - this patch breaks iwlwifi in >=3.4.83 for at least some people, including me and my Intel(R) Centrino(R) Ultimate-N 6300 AGN, REV=0x74. Reverting the patch so far has been a workaround. Before sending, I also tried out 3.4.83 + current stable-queue to make sure the problem persists.
