Let me spare a few more words. You had an initial problem: the queues were stuck. From my experience based on other bug reports, this can be worked around by limiting the bandwidth to 20Mhz on 2.4GHz. There is a known issue in this area. When the queues are stuck, the driver resets the firmware and hence you saw the firmware crash message in dmesg. You reduced the bandwidth to 20Mhz and you stopped seeing the stuck queue message. You have now a different issue: the firmware gets stuck: the watchdog interrupt fires. This is a typical firmware issue which needs to be debugged using firmware debugging tools.
