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.
