syz.0.28/4363 is trying to acquire lock:
ffffffff8cb14860 (console_owner){-...}-{0:0}, at: console_trylock_spinning+0x185/0x3f0 kernel/printk/printk.c:1879

but task is already holding lock:

ffff8880b8f2a218 (hrtimer_bases.lock){-.-.}-{2:2}, at: __hrtimer_run_queues+0x662/0xcf0 kernel/time/hrtimer.c:1752

which lock already depends on the new lock.


the existing dependency chain (in reverse order) is:

other info that might help us debug this:

Chain exists of:
  console_owner --> &rt_b->rt_runtime_lock --> hrtimer_bases.lock

 Possible unsafe locking scenario:

       CPU0                    CPU1
       ----                    ----
  lock(hrtimer_bases.lock);
                               lock(&rt_b->rt_runtime_lock);
                               lock(hrtimer_bases.lock);
  lock(console_owner);
