Not sure. My hope is that AMCC find a solution quickly. They should receive 
the failing board this week.

And they already did send a "fix" (more a workaround) for this problem:

[PATCH v2] ppc4xx: Fix DDR2 auto calibration on Kilauea 600MHz

which you rejected. So I suggest to wait for a few days.

Victor, Adam, did you already receive my board?

Best regards,
Stefan
