--- Comment #10 from Robin Haberkorn <robin.haberk...@googlemail.com> ---
I just had the same crash apparently and will upload my logs as well. It
happened on 14.2-RELEASE. And yes, I do use Bluetooth and there are quite a few
Bluetooth devices around.
kgdb quickly reveals a NULL-pointer dereference (chanctx_conf->def.chan ==
NULL). But I will spare you the details since b...@freebsd.org did already guess
it from the previous report. I will happily do some more debugging with my
vmcore on your request. I am not really willing to share the vmcore file,
though.
I don't understand this code enough to see whether it is valid that this
pointer can be NULL. At least it is checked in other functions like
iwl_mvm_bt_coex_notif_handle(). So I would suggest to simply add another
NULL-pointer check to the existing if-statement in iwl_mvm_bt_notif_per_link().
And I would add the same to iwl_get_coex_type() as well.
On the other hand, this pointer becoming NULL might have a deeper meaning and
point to another problem. But even then, it could make sense to add an
assertion after fixing the underlying problem.
