[Behre, Frederik - LT]

Hello=20

I compile my kernel with=20
pm82x_deconfig and PCI disabled.

Did I forgot something ??

After error Oops: kernel access of bad area, sig: 11 [#1] the Board
restarts.

Thanks for Helping

Why do you use pm82x_deconfig with a MPC8260  processor?  You  should
use pm826_deconfig instead.
