Hmm, what is this interrupt doing anyway? Obviously it's not really needed. I thought it's commented out because it's shared with another interrupt with a different priority, just like in my case. There must be a race condition hidden in extintr.c somewhere :/

There is no node for the Ethernet part. If there were one we wouldn't have a problem with it - as it is I have to assign it an interrupt by hand.

The NewerTech config tool allows to have all caches enabled - utterly stable here. Maybe I should run some benchmarks to see if it has any effect at all.
