Please could you clarify why you believe that this is related to Ethernet? I.e. does the problem not happen when you're not using Ethernet (but rather wifi or no networking at all)? Does the problem start to happen when you plug in the Ethernet cable, having previously booted the machine without being connected to the network? Where does the CPU spend its time when the problem occurs? Basic question: does your CPU fan work? Nothing is obstructing the airflow (e.g. dust)? If you're using fancontrol in order to regulate the fan speed, it is set up properly to prevent overheating? HTH, Jan
