Well I have done it this time, really bricked my system!

I loaded an image with a bug that causes the system to crash and reboot. No big
thing, I have done this a number of times. However my normal recovery scheme is
not working this time. I have covered this previously and described the procedure.
This time, no-go.

I think I have identified the situation that causes the ENC28J60 Ethernet port to
stop working. If the packets are not unloaded from the Ethernet chip fast enough
the fifo will fill and result in the receive error. This error must be deliberately
cleared before the chip will return to normal operation.

I am trying to figure where to go from here.
