Hack upstart or disable the service that brings the switch ports up, and bring them up manually...

Dumb question, but if you get errors like this, how can you test anything at all in the patches that you submit?

Not really. That error might be related - something indicating a breakage in the top-level (fec IIUC) MDIO controller, or not. There was "recent" rework almost everywhere. For example commit 35da1dfd9484 ("net: dsa: mv88e6xxx: Improve performance of busy bit polling"). That also hooks into the mv88e6xxx cascaded MDIO controller (mv88e6xxx_g2_smi_phy_wait), so there might be something there.

Do you have a timeline for when the regression was introduced? Commit 35da1dfd9484 reverts cleanly, so I suppose giving it a go with that reverted might be worth a shot. Otherwise, a bisect from a known working version only takes a couple of hours, and shouldn't require other changes to the setup.
