WARNING: possible circular locking dependency detected

udevd/4760 is trying to acquire lock:
ffffffff8c3139a0 (console_owner){-...}-{0:0}, at: console_lock_spinning_enable+0x2c/0x60 kernel/printk/printk.c:1802

but task is already holding lock:
ffff8880b902a258 (hrtimer_bases.lock){-.-.}-{2:2}, at: __run_hrtimer kernel/time/hrtimer.c:1689 [inline]
ffff8880b902a258 (hrtimer_bases.lock){-.-.}-{2:2}, at: __hrtimer_run_queues+0x59a/0xb60 kernel/time/hrtimer.c:1749

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:
