I thought it was gone here, but... During a run of two cpu pigs and a top display with two times of 50% cpu usage and idle time again at 50% I suddenly have seen an init with 100% cpu and idle time now at 0%. This seems to be a good hint, when an aout init fixes that problem. Even after running in normal state, make -j4 world and idle tending to 0%, I have seen a fallback to the strange behaviour, but no boot in the meantime. There must be events that lets the system switch between those states.
