------------------------------------------------------
kworker/1:2/1933 is trying to acquire lock:
ffffffff8c9142a0 (console_owner){....}-{0:0}, at: console_lock_spinning_enable+0x2c/0x60 kernel/printk/printk.c:1802

which lock already depends on the new lock.

other info that might help us debug this:

Chain exists of:

 Possible unsafe locking scenario:
