       &lt;0&gt; &lt;0&gt;  I have tried recompiling the kernel from scratch, no avail, redoing the file system, same thing. I reduced to the very basic components and see the same results. I have configured /etc/rc to do nothing with ehternet on power up init. After the board comes up, I connect (nios2-terminal) see all the messages go by, and as soon as I enter "dhcpcd -NRY&amp;" at the console, I get these messages.  Please lend a hand to a fellow engineer,  Thanks,  Carlos

I have found it! Even though the description for interrupt "0" says that it can be used for the system timer it is not.  As a general rule you should never use interrupt "0" for anything. I did this and the problem was resolved immediately.

Great!  I will update the wiki about the irq 0. Could you write a howto about dhcpcd on the wiki? It would be very helpful.
