we were thinking to some problem like:

http://www.nabble.com/USB-support-on-mpc5200-broken-td19658810.html

or

http://www.nabble.com/MPC5200-PCI-interrupt-routing-p19608472.html

Sounds like a wrong or missed clock configuration. Is your "CDM 48 MHz 
Fractional Divider Configuration Register Field Descriptions (0x0210)" setup 
correctly?

Some kernel revisions guesses and fixes the setting, some other not.
