--------------------------------------------
modprobe/9809 is trying to acquire lock:
ffff8880288be958 (&qdisc_xmit_lock_key#5){+.-.}-{3:3}, at: sch_direct_xmit+0x153/0x4b0

but task is already holding lock:
ffff88810f356958 (&qdisc_xmit_lock_key#5){+.-.}-{3:3}, at: sch_direct_xmit+0x153/0x4b0

other info that might help us debug this:
 Possible unsafe locking scenario:

       CPU0
       ----
  lock(&qdisc_xmit_lock_key#5);
  lock(&qdisc_xmit_lock_key#5);

 *** DEADLOCK ***

 May be due to missing lock nesting notation
