mmmhh... yes indeed the log file looks like the network receive thread is locked for some reason. Indeed, it could be related to a problem around the network interface. We already had to manage a similar issue with a Thunerbolt Ethernet plugged in the MacBook after the wake up from sleep while it was plugged in when going into sleep mode. The problem is not related to the network itself, it's safe to disconnect/reconnect from any network, but it seems that CopperLan is not notified and/or can't manage properly the events occurring on network interface changes on Mac.
I'll try to reproduce and fix, but in the meantime please check that your network interface is connected before waking up the computer.
