hm, there were multiple problems in this area and a lot of dormant bugs. Do you have this recent upstream commit in your tree:
| commit fcb43042ef55d2f46b0efa5d7746967cef38f056 | Author: Zhang, Yanmin <yanmin_zhang@linux.intel.com> | Date: Tue Jun 24 16:06:23 2008 +0800 | | x86: fix cpu hotplug crash | | Vegard Nossum reported crashes during cpu hotplug tests: | | http://marc.info/?l=linux-kernel&m=121413950227884&w=4
