Hm, this didn't help.

Isn't lspci just listing ASPM _capabilities_ there? Booting with
pcie_aspm=off showed almost the same output:

http://nerdbynature.de/bits/3.4.0/tg3/lspci_aspm.diff.txt

So, the workaround for me is to disable "scatter-gather":

ethtool -K p2p1 sg off

With that, no more errors show up and the interface keeps working.
