Hi Simon
As mentioned before I noticed Ethernet (on-module USB ASIX chip) to be broken on master while it still worked fine in v2016.01. I kind of remember having once noticed something along those lines when testing some of your early dm stuff but could not find our discussion about it anymore plus I don't think it did actually lead anywhere.
FWIW it currently crashes as follows (showing Colibri T20 but the same happens on Colibri T30):

Do you have any clue what could be going on?
