Note Serge's fix also fixed a mystery hang/crash on a -tip testbox that
has been broken since the merge window. Last night it produced a straight
series of 550 bootups - previously it would crash/hang after 20-30
iterations. (i did not report it in this thread before because it's a new 
testbox with just a few weeks of track record and thus i could not exclude
potential hardware trouble)

So the bug is very much fixed.
