I have a custom board that running on MCF5271.
The board is just fine when booting from flash; but has a strange
error when loading root fs from NFS, the FEC ethernet driver could not
open eth0:

In kernel setting, I used FEC ethernet controller (of ColdFire and
some i.MX CPUs), uClinux-dist 20090618 + patch 20100315, Toolchain
Codesourcery 2010.09.
Does anyone have any idea about this problem?
Thanks.
