Digging a bit deeper, this would *appear* to be one of a couple of possibilities; 1) brcmf_sdio_hostmail() is missing code to handle a response of type 0x40012 2) The firmware is failing when asked to handle the new requiests, and is going to la-la land. Decoding the reply gives us HMB_DATA_DEVREADY or-ed with 0x40010 Since the upper half-word is masked, that leaves us with 0x10 which does not appear to be a defined state. The driver does not handle this well, in any event. My guess is that you are working on top of newer firmware than I have. Can you let me know what the latest public firmware is, and where I can get it? I have version wl0: Aug 29 2016 20:48:16 version 7.45.41.26 (r640327) FWID 01-4527cfab Thanks, -Ian
