If I boot the system with earlyprintk enabled (as I've been doing throughout my dev), things work as expected. But if I boot with earlyprintk disabled, then the system does not "see" the PCIe board, because reading the vendor ID returns 0xffffffff. What we think is happening, is that when earlyprintk is disabled, the system proceeds much faster through the various inits, and the PCIe init happens when PCIe link training has not completed yet. If that is the case, then it seems I would need to check the link state in my probe function. Or would there be some other solution I haven't thought about? Regards.
