Note that this doesn't necessarily mean that the ethernet driver disables the interrupts for a too long time, it just means that the computer is only servicing the network interrupts at that time, and since the mouse interrupt does have a lower priority, it's serviced not very often and with huge delays. In such a case the network driver should either use interrupt mitigation if the cards supports it (reading many packets per one interrupt) or switch to a polled mode. > Does that seem to match your observations?
