Further testing has shown that this isn't restricted to warm reboots, it
happens from cold as well. In addition, the exact timing of the failure
seems to vary, some boots have got further before failing.
    
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
I removed the second core from the dts file rather than truly disabling
SMP in the kernel config. Doing this allowed the board to boot reliably.
