This problem was reported recently on another list.  I briefly
looked into it - the message is machine-dependent, but it really
is a problem in the way xi works.  Maybe something it do with
the vlan integration?

I have some patches for the xi driver to deal with broken
multicast (and hence fix IPv6 support).  I am also looking
at data alignment problems and problems with the Realport
cards not finding the PHY.

I have tested the driver with a CreditCard 10/100 before
and it worked correctly.  My Creditcard 10 is currently
working on an early 1.5 vintage system.

I'll look into it.
