Since this seems to be related to CPU down event, you could run a
tight loop like this overnight (for all CPUs in the system):

while :
do
echo 0 > online
echo 1 > online
done


This, maybe in conjunction with some other test like LTP or make -jN bzImage,
is usually enough to capture all CPU-hotplug related problems.
