It looks like that the chip does not repsonse to memory acces.

So the access timeout.

Please use scope or LA, to look at pci bus lines, frame, irdy, trdy , ad[].

within a short pci memory registers access loop.

Check the altera pci core config page 4.

Try config the e1000 to a lower memory address in pci mmemory space,

and check the memory access.
