Note: I tried to find Mikko's config, but zlin.dk times out. So I cannot 
check that he actually has CONFIG_HOTPLUG_CPU off, which is probably 
required to actually trigger the bug. 

But it does sound likely.

However, the "Thunderbird crashes out for me" thing in that same thread 
may be totally unrelated.
