Unfortunately I don't have any 8641 boards near me, so I can't
debug this myself. Though, I tested gianfar on MPC8568E-MDS with
2.6.33 kernel, and it seems to work just fine.

I see you use SMP. Can you try to turn it off? If that will fix
the issue, then it'll be a good data point.

Meanwhile, I'll try SMP kernel on MPC8568 (UP), and let you
know the results.

Thanks,
