I opened https://bugzilla.kernel.org/show_bug.cgi?id=57681 to keep track of this and attached the dmesg logs you collected. If you have a chance, could you also collect and attach the output of "lspci -vv" (any kernel is fine for this). I don't see anything obvious wrong, at least from the PCI side. Maybe the atl1c guys will have some ideas.
