Could you try this on 2.6.13-mm2? If this is due to a sending broadcast
IPI related issue that should fix the problem.
I should say i didnt try i386 in a while
but i suspect some of the recent suspend/resume code required some
modifications to the i386 hotplug code which might be getting in the way
if you just try logical cpu hotplug alone without using it for suspend/resume.
Shaohua might know more about the status.
Cheers,
