Using Anthony's tree I was able to reproduce the failure. Why it worked with my testing previously I have no idea :-( The problem was that the local processor APICs were not marked disabled for the processors not being active. I also changed the code to mark unused processors as disabled in the MP table, though that seemed to have no impact on this particular failure. With this version I can boot Ubuntu all the way to X using Anthony's tree. Sorry for the noise, I am still mystified :-( Cheers, Jes
