I managed to reproduce it after a couple of reboots and, unsurprisingly,
it's a race condition. See commit 4df28d9 for more info.
If that doesn't fix it for you I hope the other logging (and unrelated)
improvements I pushed will help you get something useful from `grep
spoof-mac /var/log/syslog` to report back.
