Not quite sure where to report this.
Since v5.4-rc1, at shutdown I'm seeing a hang with this message repeated
in /var/log/messages:
unregister_netdevice: waiting for ens1f0 to become free. Usage count = 1
Google turns up this particular failure off and on for the past few years
from various network devices. It's currently 100% reproducible on my rig.
ens1f0 is a FastLinq NIC in iWARP mode:
01:00.0 Ethernet controller: QLogic Corp. FastLinQ QL41000 Series 10/25/40/50GbE Controller (rev 02)
Subsystem: QLogic Corp. FastLinQ QL41212H 25GbE Adapter

(the network switch is powered off at the moment).
