Anyone seen this when booting 2.6.15-rc1 on 8xx?

The kernel boots just fine into user space so it seems harmless, but I
suspect it will bite me later.


I am currently working with 2.6.15-rc1 on MPC852 and I am seeing a similar
problem.

Have not had time to look at it yet, however I was not getting this on
2.6.11.
