Recently installed 6.0.2 on a new SSD in an older system (while a new one was on order). �Changed sources.list to point at "testing" and updated.
When the new system arrived, we swapped the SSD into it and now get "unknown MAC, using family default".�"ifconfig eth0 up" simply says�"Error fetching interface information: device not found"
