IGOR MAC with DP83848C in uClinux

I have a DE3 with the multimedia HSMC board that contains the National Semiconductor DP83848C. This setup is very similar to the NEEK. I'm trying to get the Ethernet to work in order to transfer files. I copied the Ethernet setup from

neek_ocm_spi_mmu.zip (http://www.nioswiki.com/@api/deki/files/345/=neek_ocm_spi_mmu.zip),

which uses the IGOR MAC after several unsuccessful TSE attempts. I follow the instructions here:

http://www.nioswiki.com/operatingsystems/uclinux/ethernet

and select

[*] Network device support

[*] Ethernet (10 or 100Mbit)

[*] Opencores (Igor) Emac support

Device Drivers -->Network device support ─>

[*] Network device support

[*] PHY Device support and infrastructure --->

[*] Drivers for National Semiconductor PHYs

Network Applications --->

[*] mii-tool (in --- Net-tools section)

I hook the ethernet into an isolated hub, which also contains another PC with IP = 192.168.1.254 (any IP.. they all do the same thing).

it ends up with kernel panic when I try to ping:

Kernel panic - not syncing: Oops

I've also enable

[*] Generic Media Independent Interface device support

to get mii-tool to compile into the kernel image

and tested

[*]OpenCores 10/100 Mbps Ethernet MAC support

but neither make it work.

Any ideas?
