Just my thought on how to debug that: I'd try to bisect the pci init routine in the boot loader. I.e. first only do the first half of the initialisation in U-Boot. Depending on Linux being able to boot or not initialize more or less on the next run. Maybe there is a single register write that makes Linux fail?!
