--- Comment #3 from ml at netfence.it ---
Hello.

As I said, I added the proposed patch a long time ago and had no such panics
for more than a year.

However my laptop had another one yesterday.



ani_state->listen_time is in fact 0!

This is strange, since I don't think anything should change it between 
    ani_state->listen_time += listen_time;
and
    ofdm_phy_err_rate =
        ani_state->ofdm_phy_err_count * 1000 / ani_state->listen_time;

Is it possible somthing changed this in another thread? (Please forgive my
ignorance of the kernel if it's something that stupid).

In any case, I'm enabling AH_DEBUG in the kernel.



P.S. In the meantime I upgraded to 10.3.
