Hi,

I try to get 2.6.25.6 running on Freescale's MPC8641D-HPCN (Processor is revision 1), but somehow the PCI express controller setup fails:

PCI: Probing PCI hardware
PCI: 0000:00:00.0: class b20 doesn't match header type 01. Ignoring class.
PCI: 0001:02:00.0: class b20 doesn't match header type 01. Ignoring class.

PCI: not setting up bridge 0001:02:00.0 for bus 3
PCI: Enabling device 0001:02:00.0 (0106 -> 0107)

- PCIe worked with 2.6.20.7 on this board, but unfortunately SMP support was not ready then. 
- on MPC8610-HPCD, PCIe works with 2.6.25.6, so I wonder what could be the difference.

Any ideas?

Best regards,
Reinhard
