extract from /var/log/messages with KASAN output

The broadcom bwn Wifi driver causes a kernel panic soon after a connection =
with
an encrypted network is established. Soon means: immediate to approx. 30sec.
after the connection is established.

- This did not happen with FreeBSD RELEASE 13.x
- This does not happen when connecting to an unencrypted network
- It crashes both with CCMP and TKIP encryption

Hardware:
=E2=80=94=E2=80=94=E2=80=94=E2=80=94=E2=80=94=E2=80=94=E2=80=94=E2=80=94-
Macbook Pro 3,1 with Broadcom BCM4321 wireless card

Setup:
______
At boot time, the bwn_v4_ucode firmware module is not loaded, the machine g=
oes
up and running.
When subsequently the firmware is loaded and the interface restarted,
it crashes after the connection is established.

  kldload bwn_v4_ucode
  service netif restart

The WLAN is a 2,4GHz 802.11g network.

wpa_supplicant.conf:

network=3D{
        ssid=3D"SomeNet"
        psk=3D"SomePassword"
        pairwise=3DTKIP      # or CCMP
