The "no space" and "failed to assign" messages are all for bridge windows (13 is the I/O window, 14 is the MMIO window, 15 is the MMIO pref window). I can't tell if you have any devices below these bridges (lspci would show them). If you don't have any devices below these bridges, you can ignore the messages.
