Yes, sorry :) Neuron short circuit.

The dmesg is rather long, but maybe the list of mps related messages wil be enough? (output follows at the end of the message)

Next thing to try :)

boot -v yields the following messages. Curious thing, I don't see the backplane as a device. Shouldn't it show up? I guess it would be that "edge expander"
