WARNING: possible circular locking dependency detected
6.1.83-syzkaller #0 Not tainted

syz-executor359/3540 is trying to acquire lock:

ffffffff8d11ede0 (console_owner){....}-{0:0}, at: console_emit_next_record+0xa9c/0x1000 kernel/printk/printk.c:2768

but task is already holding lock:

ffff8880b992a4d8 (hrtimer_bases.lock){-.-.}-{2:2}, at: hrtimer_start_range_ns+0xd8/0xc50 kernel/time/hrtimer.c:1297

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:

 Possible unsafe locking scenario:
