It's an AM2 5600 chip on AMD 690G chipset on Asus M2A-VM board.
With CONFIG_SLUB it panics. With CONFIG_SLAB all is well. (Same behaviour on
2.6.22-rc1 also)
Unfortunately, it panics so early, it doesn't make it to serial console. So
here's what I have written down (sorry if I missed some important info; I hope
it gives a clue or two):

The .config is attached (with the CONFIG_SLUB).
(It's vanilla 2.6.22-rc2 plus a patch, which is submitted to libata maintainer
already, from Tejun Heo for SB600 AHCI to work on a system with >4GB.)
Any patches welcome.
Thanks

sysfs? If you build without CONFIG_SLUB_DEBUG then SLUB will not use
sysfs. You can switch that off in the embedded section.

Fair enough. Would you the section name it appears in 'menuconfig'?
I looked under 'Kernel hacking' section (where the slab debugging appears if
slab is turned on as 'Debug slab memory allocation') & in the 'General setup'
section also. I unable to figure out how to disable slub debugging :-(.
Pls give me a pointer to it.
Thanks
(Won't it be right to disable it by default when a user selects slub such that
a user needs to manually turn on the slub debugging in menuconfig?)

SLUB_DEBUG is both "bool if EMBEDDED" and "depends on SLUB", which
means just getting it to be visible in "menuconfig" is quite a challenge :-)
You first need to go into the choice where you pick the allocators ("Choose
allocator --->" which is the last option in General Setup), and then pick
SLUB as your allocator.
Then, from the General Setup again, turn on the "Configure standard
kernel features (for small systems) --->" just above the previous option
and then go into that menu. Now the option to disable SLUB_DEBUG
(which is y by default) becomes visible, so just deselect it to disable it.

Thanks for that. I've just figured that out a few minutes ago :-). Was a
tricky one indeed. Then I captured and posted the current kernel bug report
while having slub just then.
Thanks

Well this indicates that something destroys the sysfs pointer structure
that SLUB is using. Could you reenable CONFIG_SLUB_DEBUG and boot with the
option "slub_debug" on the kernel command line?
Also enable the list debug options in kernel hacking.
This should show up on the console since the failure is in slub_sysfs_init
which is long after the console has been enabled. I wonder why it did not
show so far?

Hmmmm..... We have seen this before
http://marc.info/?l=linux-kernel&m=117891943401284&w=2
I suspect this is due to an interaction with other debug flags you have
set. What I see in your .config is
CONFIG_DEBUG_RT_MUTEXES=y
Try to switch this off if switching off the lockdep flags does not hel.
CONFIG_DEBUG_PI_LIST=y
Will go off with the above
# CONFIG_RT_MUTEX_TESTER is not set
Leave off
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_MUTEXES=y
Try toggling if the disabling lockdep flags does not work.
CONFIG_DEBUG_LOCK_ALLOC=y
CONFIG_PROVE_LOCKING=y
CONFIG_LOCKDEP=y
I suspect the above are the main candidates for trouble. Could you
switch those off?
# CONFIG_DEBUG_LOCKDEP is not set
CONFIG_TRACE_IRQFLAGS=y
CONFIG_DEBUG_SPINLOCK_SLEEP=y
# CONFIG_DEBUG_LOCKING_API_SELFTESTS is not set
CONFIG_STACKTRACE=y
# CONFIG_DEBUG_KOBJECT is not set
Debug kobject may be helpful.
CONFIG_DEBUG_BUGVERBOSE=y

Yes, sounded the same to me too: I couldn't reproduce it or see anything
wrong in the code back then. But Srihari's info about CONFIG_DEBUG_SLUB
off has helped a lot: I was then able to reproduce it on my x86_64, and
after a lot of staring at the code, the problem became obvious...
[PATCH] slub: fix size adjustment when SLUB_DEBUG off
SLUB was corrupting the anon_vma's spinlock when not configured for
SLUB_DEBUG: the size adjustment necessary for SLAB_DESTROY_BY_RCU or
constructor was inside the CONFIG_SLUB_DEBUG appropriate for poisoning.

Right. The #ifdef CONFIG_SLUB_DEBUG is at the wrong location. The best fix
is to moving the #ifdef otherwise the size is still wrong for the
ctor case.
SLUB Debug: Fix object size calculation
The object size calculation is wrong if !CONFIG_SLUB_DEBUG because
the #ifdef CONFIG_SLUB_DEBUG is now switching off the size adjustments
for DESTROY_BY_RCU and ctor.

Yes, I think that should do it too. The reason behind my repeating
the block was to handle the case where SLAB_POISON is passed to
kmem_cache_create, but CONFIG_SLUB_DEBUG is off. But apparently
that case would hit the BUG_ON(flags & ~CREATE_MASK), therefore
your patch is simpler and better. Quite a maze.

This was an effect of me suggesting to switch off CONFIG_SLUB_DEBUG. If
you did not run without CONFIG_SLUB_DEBUG then you were not affected by
the problem. And the earlier case that you reported was a version of SLUB
that did not have the capability to switch off SLUB_DEBUG.
Is there any way we can boot with "slub_debug" on the kernel command line
and get early printk output? Looks like an early failure that may have to
do with other kernel debug options being on (lockdep or so?)

Sure, I will try that as well. For reference, the last kernel tested on
that box was HEAD 129a84de2347002f09721cda3155ccfd19fade40.

Are you sure? If CONFIG_EMBEDDED=y then -rc1 and -rc2 give you the
choice to turn it off.

Right. That went in indeed shortly before the rc1 release.
So if both had disabled SLUB_DEBUG then this could be the reason for the
failure. However, CONFIG_SLUB_DEBUG was set in the .config that was
included when this bug was reported. So I think we still have not found
the real problem yet.
Ok booting SLUB without "slub_debug" and having
CONFIG_DEBUG_LOCK_ALLOC
CONFIG_LOCKDEP
will trigger the problem.
So I guess the issue is that lockdep does a slab alloc while we get the
slab lock during slab alloc?

Lockdep is not available on IA64 where I would be able to figure it out
using a simulator. x86_64 early printk support seems to be broken?
No output with earlyprintk=serial.

If I have CONFIG_SLUB_DEBUG set, then box boots fine. If I don't have it
set, then it hard hangs sometime after boot:
[...]
ReiserFS: sda2: Using r5 hash to sort names
VFS: Mounted root (reiserfs filesystem) readonly.
Freeing unused kernel memory: 180k freed
which is usually followed by messages bringing up the network link, etc.
Let me know which tests you want run, or which patches to try.

Just another data point: with the flick of CONFIG_SMP, I'm in control of the
hangs/crashes ;-).
Yup, with CONFIG_SMP=n, I'm unable to reproduce the problem. It's quite stable
actually (having completed a dozen kernel compile sessions so far).
I suspected this after seeing spinlock issues on both cores of my CPU in my
earlier report. Just a stab in the dark with some unexpected luck :-).
(Tested on http://www.kernel.org/hg/linux-2.6 changeset at 57106:3f42ad5de7cd.
That's the latest hg commit there.)
Thanks
PS: For the record everything except sysrq support is disabled in the kernel
hacking section. Also the CONFIG_SLAB_DEBUG is off. Kernel preemption is also
off, after proving it had no influence. Just to keep the test case simple.

could you enable CONFIG_PROVE_LOCKING - does it spit out any warning
into the syslog?

Compiled slub with SMP & CONFIG_PROVE_LOCKING. No luck. It still hangs solid
after the second spinlock lockup call trace.
Here's the relevant sections of the kernel logs:

hm. This suggests that the spinlock got corrupted - otherwise lockdep
would have complained about the lockup before the spinlock-debug code
had its chance.
> Surprisingly, with CONFIG_SMP=n, CONFIG_PROVE_LOCKING produces this
> with slub (then hangs solid):
yes - PROVE_LOCKING reactivates spinlocks even on UP. At least this
suggests that you'd have gotten the hang even with maxcpus=1 - i.e. the
spinlock corruption is not caused by some genuine SMP race.
furthermore, PROVE_LOCKING also turns on DEBUG_LOCK_ALLOC, so we now
know that it's most likely not use-after-free type of corruption.

You're right on the mark there: even with maxcpus=1 or nosmp (or with both),
with PROVE_LOCKING it hung with slub. I didn't mention that so not to confuse
the matter, but you rightly figured that out too.
Thanks

You've made no mention of trying the patch I sent yesterday, or better,
the patch Christoph replied with to replace it. Please clarify whether
you're getting the above after applying one of those patches - thanks.

So you are able to run slub with the patch and
1. CONFIG_NUMA set (CONFIG_SMP works fine here too)
2. CONFIG_LOCKDEP
3. CONFIG_DEBUG_LOCK_ALLOCS
?
That fails here.

I didn't say that. Previously a kernel without SLUB_DEBUG set would not
work, with the patch it does. That is all I tested so far.

Sorry about that :-(. Was a busy day & skipped a few emails :-(.
Indeed with Christoph's patch (over the hg commit 57109:745e2df8ec60), without
CONFIG_SLUB_DEBUG, but with CONFIG_PROVE_LOCKING only under the kernel
debugging section, on CONFIG_SMP the slub kerenel is quite stable. (It's
running some stress tests now, but things are looking good.)
(If you want me to test it with other slub or kernel debug options please let
me know. It just takes a lot of time to eliminate the variables, if there are
problems.)
Thanks folks.

Yup. compile with
CONFIG_NUMA
CONFIG_LOCKDEP
CONFIG_DEBUG_LOCK_ALLOCS
and then try to boot without slub_debug.
If that fails then boot with slub_nomerge

That works for me with the patch, .config attached.

Yup done that. The resulting kernel (without CONFIG_SLUB_DEBUG=y) is quite
stable; passed a few iterations of kernel compile tests successfully.
> and then try to boot without slub_debug.
I guess you mean with CONFIG_SLUB_CONFIG=y? If so, I built another kernel with
CONFIG_SLUB_DEBUG=y (plus all of the above) & tested it. It panics by default,
but with slub_nomerge it works just fine (tested under moderate load).
(the panic message produced by CONFIG_SLUB_DEBUG=y was the exact same call
trace as my very first email in this email thread with slightly different
address on a couple of functions, but rest remains the same)
I'm personally very happy that slub works stably without slub debug options,
because that's what I'd run in a production env. Thanks to your patch, slub is
quite stable without the slub debug for me :-)). But it'd to nice to have a
working slub debug for test env., as you'd undoubtedly be aware of, of course
:-). Just my humble opinion.
> If that fails then boot with slub_nomerge
Yup, I had to use slub_nomerge; without that CONFIG_SLUB_DEBUG=y kernel
panics. (I haven't tested the UP case though. I did try nosmp & maxcpus=1, but
they had no effect on the panic. Do you want me to test UP case for
CONFIG_SLUB_DEBUG=y without slub_nomerge?)
Thanks

Hmmmm... That means the .config sent initially here was bogus.

Hmmm... Bad. We have conflicting reports and no clear way to trigger the
bug. This may actually only trigger depending on how certain objects is
place in memory.
Could you boot with slub_debug and then run
slabinfo -v
to validate all slabs? If there is anything wrong with an object then it
should show in the syslog.
slabinfo.c can be found at Documentation/vm/slabinfo.c

See Documentation/vm/slub.txt which covers most of those.
slub_nomerge is not mentioned. It removes an optimization and that is only
useful for debugging strange cornercases. I hope to remove it someday.

?
Considering we're trying to help you fix bugs in your code, you could be
considerably more helpful.

I am trying figure out what is wrong and somehow that is not helpful? The
data that we have right now about the bug does not give us a clear
picture. One explanation that would have made it consistent would be that
the .config posted was not reflecting the actual kernel in use.

Right. "slabinfo" output is useless. You need to specify -v for it to have
any effect.
slabinfo -v
can detect object corruptions without the kernel having to touch the
object. It will scan all objects and it will only work if run as root.
Any corrupted objects will be reported to the syslog.

(Only only could have made that sentence better.)
Sorry I didn't know slabinfo -v produces nothing on stdout, stderr, rather all
findings reported to syslog. Right? You don't have to answer this question, if
my assumptions are right.
If so, when ran it produced nothing in the syslog.
Sorry mate, I'm unable to spend a lot of time on slub debugging. I'll
nonetheless keep slub as my preferred memory allocator for the rest of the
2.6.22-rc process. If anything interesting turns up that I could contribute
during this phase, you'll be the first know I promise.
Thanks

You are doing what you are supposed to do, fixing your broken code. We
are the ones that are helping you do that, by reporting the problem and
testing solutions. I think you have your attributions backwards.

The .config I sent is the one that the last boot of the machine was
based on. The kernel is 2.6.22-rc2 with the patch moving the #ifdef from
you, and it works for me with or without CONFIG_SLUB_DEBUG set.

I was not talking about your config but the .config that started this
thread.

OK, that also wasn't clear.
I'll repeat, if you want me to test anything further, please let that be
known explicitly. I have reported what works and doesn't, as far as I'm
concerned the patch works for me without incident.

I finally figured out the second issue. Took some time to get that figure
out. Sorry. But now all the bug reports make sense.
Here is the fix
SLUB: Fix NUMA / SYSFS bootstrap issue
The kmem_cache_node cache is very special because it is needed for
NUMA bootstrap. Under certain conditions (like for example if lockdep is
enabled and significantly increases the size of spinlock_t) the structure
may become exactly the size as one of the larger caches in the kmalloc array.
That early during bootstrap we cannot perform merging properly. The unique
id for the kmem_cache_node cache will match one of the kmalloc array. Sysfs
will complain about a duplicate directory entry. All of this occurs while
the console is not yet fully operational. Thus boot may appear to be
silently failing.
The kmem_cache_node cache is very special. During early boostrap the main
allocation function is not operational yet and so we have to run our
own small special alloc function during early boot. It is also special in
that it is never freed.
We really do not want any merging on that cache. Set the refcount -1 and
forbid merging of slabs that have a negative refcount.

Impressive Christoph. Indeed, this fixes my problem on latest -git (its hg
equivalent :-)). Well done.
(Tested with CONFIG_SLAB_DEBUG without slub_debug; all was well. Then with
slub_debug & slabinfo -v also; again all was well. I had many LOCKDEP and its
relatives also compiled in.)
Now hoping it'll be in 2.6.22-rc3 :-)).
