My lockup (due to wrong firmware) was caused by the function
ath6kl_bmi_get_lkahd in bmi.c. The function was called with the parameter
"need_timeout = false". This causes the while loop to wait for a response from
the chip. Since the wrong firmware image was used, the chip will never respond.
Is it possible for the ath6kl driver to somehow read the firmware version from
the firmware file before sending it to the chip?
