Hi all I am using MPC8248 based board which has got one PCI interface at 66 MHz .
I am not able to initialize PCI, I am really clueless and getting the following errors. Can any one tell me what is wrong with this? But I am initializing the pci in uboot also and there in uboot able to detect the network card, but while boot its give first time the machine check exception and then its reseting itself and then in second try it (uboot) is working fine. Do the register sets in uboot is again read by linux during linux PCI initialization? Someone please help. ## Booting image at ffd00000 ...
