Could you post the output of: lspci -vvv -xxx with the "PCI: mvebu: Convert to PCI emulated bridge config space" patch applied and reverted, and send the result ? This would allow me to look at the differences in the configuration space exposed by the emulated bridge and hopefully see which one might cause the regression.
