syz-executor.1/3436 [HC0[0]:SC0[0]:HE0:SE1] is trying to acquire:
ffff88808b75ea98 (&new->fa_lock){.-.-}-{2:2}, at: kill_fasync_rcu fs/fcntl.c:1014 [inline]

ffff88808b75ea98 (&new->fa_lock){.-.-}-{2:2}, at: kill_fasync+0x136/0x470 fs/fcntl.c:1028

ffff88802476c948 (&timer->lock){....}-{2:2}, at: snd_timer_start1+0x5a/0x800 sound/core/timer.c:541
which would create a new lock dependency:
 (&timer->lock){....}-{2:2} -> (&new->fa_lock){.-.-}-{2:2}

but this new dependency connects a SOFTIRQ-irq-safe lock:
 (&group->lock){..-.}-{2:2}

Chain exists of:

 Possible interrupt unsafe locking scenario:
