I see a change on June 25, 2015, and a few others on that file that seem
like they could be the issue:

This isn't a final solution but the problem is in:
sock_set_flag(sk, SOCK_DESTROY);
in routine ax25_release() in file net/ax25/af_ax25.c which does what it
is supposed to do in kernel 4.1.21 but NOT in kernels 4.2.8 & above. It
should destroy & free the socket when disconnecting.
For my 4.2.8 kernel If I add this after the sock_set_flag() call in
ax25_release() then the connection is released after disconnect & I can
reconnect again.
release_sock(sk);
ax25_disconnect(ax25, 0);
lock_sock(sk);
ax25_destroy_socket(ax25);
>From the af_ax25 code in the 4.1.21 kernel, it expects sock_set_flag(sk,
SOCK_DESTROY); to
ax25_destroy_socket
ax25_free_sock
