I'm afraid not. It has only happened twice and both times I was away
from the box in question at the time of failure, so it wasn't doing a
great deal.
I'm running 2.6.24-rc2 on two boxes and both times it happened on the
box running a quad core processor.

Well, it looks like either se or pse is NULL.
Ingo, can you please have a look?
Most puzzling this, it should be guaranteed that the top sched_entities
are of the same group, therefore avoiding this loop into NULL. Obviously
something has gone wrong.
Grant, is there anything specific you can tell us about how to reproduce
