Tejun touched this code last.  :P

The commit 3a101d0548e9 "sched: adjust when cpu_active and cpuset configurations are updated during cpu on/offlining" changes stuff in _cpu_down().  If code got scheduled on an offline cpu that would cause a GPF I think.
    
I added him to the CC list.

Following up via mail.  Thanks.
Comment 3 Dan Carpenter 2010-08-24 11:52:18 UTC 
It was unrelated to Tejun's patch.  Sorry I doubted you Tejun...  :P

Fixed by:  602586a83b719 "shmem: put_super must percpu_counter_destroy"
