Looks like debian stable is going to get a kernel that crashes a few
minutes after you start using bluetooth for audio streaming to
headphones!

Happened a couple of times, within a few minutes of starting to use
bluetooth.  First time, didn't get any syslogs.  Machine was hard
locked for 30 minutes, only responded to alt-sysrq-s,u,b (sysrq didn't
otherwise log anything).

Second time, got a crash in bt_sock_poll, plenty of things still got
logged to syslog until I rebooted, but the machine was otherwise
unusable - X deadlocked, and ssh not responding.  If it's the same
crash every time, that pretty much makes bluetooth audio streaming
unusable on this machine.

https://www.spinics.net/lists/linux-bluetooth/msg88356.html

points to a patch that has supposedly already been applied to
bluetooth-next, but is definitely not in linux-source-5.10 5.10.46-4
(testing).

Current code still reads:

        /* cleanup runtime environment */
        remove_wait_queue(sk_sleep(session->intr_sock->sk), &intr_wait);
        remove_wait_queue(sk_sleep(session->intr_sock->sk), &ctrl_wait);
        wake_up_interruptible(&session->report_queue);
        hidp_del_timer(session);

Second remove_wait_queue should be: ctrl_sock->sk
