Is IRQ 1 related to network in any way?

The IP stack uses the Altera TSE drivers, which in turn use the SGDMA drivers. The SGDMA are the only components related to the network that use IRQs. You can check the SGDMA drivers and see if they are using the correct API to register the interrupts.

Please note that "stop responding to ping requests" doesn't mean that the problem is coming from the network or the TCP IP stack. It could also mean that the CPU or the operating system is completely crashed. You need to check what is going on with a debugger.
