I've some more info from failures last night: 1. I was wrong; it isn't a way early migration; it's a 2nd migration - it seems that the first migration leaves the system in a bad way 2. It is only happening on specific machines - interestingly enough, in every case, we migrate between dual core Xeon and quad core E5310 systems; these systems have different cache hierarchies I think; maybe the CPU hotplug code cant handle a change in the processor type?
