Subject: Intel Pro1000 on CN5020, hangs Uboot

Hi,

I have a OCTEON CN5020, on which I tried plugging in an Intel Pro 1000
PCI NIC. But Uboot hangs with a trap exception. Uboot has no problems
with a Realtek RTL8139 NIC PCI card that supports 100MBps. Could
someone tell me the reason for such a behaviour?

Regards,
Jack
