Firmware crash is seen randomly, because of sending wrong vdev_id in vdev_create command. This is due to free_vdev_map value being 0. free_vdev_map is getting assigned after ieee80211_register_hw. In some race conditions, add_interface api is getting called before assigning value to free_vdev_map. Fix this by assigning free_vdev_map before ieee80211_register_hw. Also, moved ar->cc_freq_hz and ar->txmgmt_idr initialization before ieee80211_register_hw to avoid such race conditions.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
