Hi Shriram, We faced a similar issue on PCI2/MPC8541 with linux 2.6.13. This version (and probably older ones) have a bug related to PCI2 ressource allocation inside the kernel (in particular due to wrong 'mpc85xx_pci1_last_busno' variable initialisation). Upgrading to the last stable kernel release (2.6.19 for sure) may help.
