Not sure if this is an actual bug since I don't have any Thunderbolt devices to test with, but on every boot:

Hardware is 2012 Macbook Ivybridge.

Hardware is 2012 Macbook Ivybridge.
Error occurs on kernels from 7bc5a2bad0b8 (which enabled Thunderbolt on Apple hardware) onwards.

I also saw this error on Macbook Pro 12 . Looks like there is no space left in the pci bridge.

Hardware is 2012 Macbook Ivybridge.
Error occurs on kernels from 7bc5a2bad0b8 (which enabled Thunderbolt on Apple hardware) onwards.

These messages can be safely ignored.

The firmware does not assign any resources to the 05:05 and 05:06 bridges (all resources are assigned to :03, :04). The kernel's pci resource allocation heuristic tries to reserve some memory/io resources for every hotplug capable bridge that it finds during boot. Here the parent bridge's resource windows are already exhausted so this fails. This is not a problem here since thunderbolt hotplug will only be done on the :03, :04 bridges. 7bc5a2bad0b8 prevents the thunderbolt controller from powering off during boot, which is why these messages appear after that commit.
