This makes sense. Before the dhclient closes the device, was the device
functioning properly? If not, was it not sending or not receiving?

If the device was functioning properly prior to the close, meaning that
the dhclient was closing because there was no response from the dhcp
server, then the stop_block error was inconsequential.
