that looks nasty ...
and -git8 should have the v2.6.23 scheduler code in essence.

ah, this is likely with the recent scheduler commits included as well,
right?
if it's reproducable, could you try with group scheduling disabled, i.e.
with:
# CONFIG_FAIR_GROUP_SCHED is not set
as that would be the main suspect for such type of a crash.

To fill in a few details. This was triggered in the middle of a
kernbench run on the machine. A job with just dbench runs in it ran to
completion. The machine is a 4 node numa x86_64 system.
Seems that most schedular options are on:
CONFIG_FAIR_GROUP_SCHED=y
CONFIG_FAIR_USER_SCHED=y
At the moment we don't have any historical jobs back from 2.6.23 so I
cannot be more specific as to when it arrived in mainline. The x86/x86_64
merge broke our build process; a bad assumption here, not a problem with
the merge.

Ok, preliminary results with this disabled seem to get us past
kernbench. I am rerunning with it enabled to confirm it blammo's.

Andy,
I have got details from Kamalesh on the machine where this is
recreatable (we couldn't recreate on other machines). Will start looking
at this tomorrow morning first thing ..

A rerun with it enabled however ran to completion. So I think we have
to assume this is at best not 100% reproducible. Seems that more
directed testing is going on now.

Dmitry found something that might explain the crash: could you check
whether the patch below fixes it?
Ingo
---------------------->
Subject: sched: fix new task startup crash
From: Ingo Molnar <mingo@elte.hu>
this should fix the put_prev_task crashes that were reported,
Dmitry Adamushko noticed that it's not valid to call into
task_new_fair() if this_cpu != task_cpu(p).

I have submitted jobs against a couple of the releases which showed this
problem with this patch. They will be a while as there are other tests
running at the moment. Will let you know when they are done.

yes - i pointed this out in a separate mail.

yes, and your fix is the better one, it goes into the next batch of
fixes.

I don't see a fundamental reason why it would be invalid to call
task_new_fair() when this_cpu != task_cpu(p). Besides, calling
activate_task->enqueue_task->enqueue_task_fair() on a new born task (as
is being done in the patch you have sent) is slightly buggy in the sense that
its p->se.vruntime is not properly calculated (because we set wakeup argument
as 0).
We (myself, Kamalesh and Dhaval) have tested the patch below, w/o being
able to recreate the problem. The patch allows for task_new_fair() to be
called even for the case when child is being added to another cpu's
runqueue.
--
Child task may be added on a different cpu that the one on which parent
is running. In which case, task_new_fair() should check whether the new
born task's parent entity should be added as well on the cfs_rq.
Patch below fixes the problem in task_new_fair.

Have that patch submitted too. Somewhen we'll have some more results.
