    Well, thanks, but I meant the source code. Please do "gdb vmlinux" and then
    "l *check_preempt_wakeup+0x6e" in gdb.

    Thanks,

    Here's the requested output:

    (gdb) l *check_preempt_wakeup+0x6e
    0xffffffff802329ae is in check_preempt_wakeup (kernel/sched_fair.c:668).

    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
    this?

    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.
