Further investigation of the issue has brought me to the conclusion that changing power source during high network traffic whilst connected to a network using ethernet causes a crash. It is my opinion that this problem is probably the e1000e ethernet driver. Below is an extract from syslog which from what I can tell has logged the effects of changing power source but not the actual crash. But it may be useful!
