I've seen that message for quite some time now.

Here's some info from the EFI shell.

Firmware puts each cell into a NUMA node, so we should really
only have 2 nodes, but for some reason, that 3rd node gets
created too. I haven't inspected the SRAT/SLIT on this machine
recently, but can do so if you want me to.

Nope, same oops.

Hm... from the boot log

ACPI: SLIT table looks invalid. Not used.

So the kernel doesn't like the SLIT; does it go off and create
its own NUMA nodes then?

May not have anything to do with the problem we are looking at but memory
setup is screwed up. Funky effects may follow.

Duh. Have to look at this in more detail.

SLIT table just contain the distances if I remember correctly. The memory
maps are separate.

Actually, I was reminded off-list by my HP colleagues that the
memory setup I showed you is common on mid-range and high-end HP
ia64 platforms.

Lee tells me:

	The third node is the "interleaved memory" pseudo-node.
	The firmware always interleaves 512MB of phys address
	space across the nodes.  On these platforms, only
	interleaved memory is at phys addr 0--needed by firmware,
	...  All the real NUMA nodes' memory starts at some high
	phys addr. So, even in "numa mode" [a.k.a. 100% cell
	local memory], the firmware must create a region of
	interleaved memory at phys 0.  So, we get N+1 nodes.

	Because node 2 is at phys 0 and contains only 512MB, it
	is all ZONE_DMA memory.  DMA zone is 1st 4G on ia64.

Our platforms have been shipping like this for years, so it's not
like anything recent has changed.

Thanks,

In the meantime, I rebuilt the kernel with vm and slub debugging
turned on, but actually nothing really informative came out
during dmesg.

Anyhow, it still oopsed, but obviously the IP was different.

Here's the new oops, with addr2line output below.

That may mean that early_kmem_node_alloc gets a screwy page number from
the page allocator? ????

Can you print the address of page returned from new_slab() in
early_kmem_cache_node_alloc()?

Christoph, we've seen similar issue on s390:

http://git.kernel.org/?p=linux/kernel/git/penberg/slab-2.6.git;a=commitdiff;hÿ64d6c42abaffdb8686c77930eafb4da5b676f5

Maybe your changes are trigger a latent bug with DEFINE_PER_CPU handling 
in SLUB?

There is no node -> cpu mapping like that in SLUB.

Garg. We did not hit the point before the crash.

Must be an insipient page_to_nid somewhere.

[-- Attachment #1: Type: TEXT/PLAIN, Size: 1375 bytes --]

Another stab at the problem:

We have the following code in init_kmem_cache_nodes()

  if (slab_state >= UP)
                local_node = page_to_nid(virt_to_page(s));
        else
                local_node = 0;


If the slab bootstrap is complete (UP) (which is the case here) then
the structure pointing to by s was allocated using kmalloc itself. So
virt_to_page() works for the typical.

The changeset results in the use of a statically allocated structure
after boot is complete. Now page_to_nid(virt_to_page(s)) runs on a
global data address.

Could this be problematic for some reasons on IA64?

The following patch makes init_kmem_cache_nodes assume 0
for statically allocated kmem_cache structures even after
boot is complete.

Dunno.  Alex or I will check and get back to you.

An allocated kmem_cache structure is definitely not in the range of the
kmalloc_caches array. This is basically checking if s is pointing to the
static kmalloc array.

Check was wrong.. Sigh...

Well, making progress (maybe?).

Now we're hitting a BUG_ON().

Interestingly, the machine now boots all the way to a login
prompt, whereas previously, it would simply hang.

Yes I think this is the fix.

Thats a kfree of an object not allocated with a slab allocator.
Recovery is easy in such a case: Dont free the object.

I don't get it.

static int sr_probe(struct device *dev)
{
	/* ... */

	cd = kzalloc(sizeof(*cd), GFP_KERNEL);
	if (!cd)
		goto fail;

	/* ... */

	fail_put:
		put_disk(disk);
	fail_free:
		kfree(cd);
}

The kfree() is balanced with kzalloc(). Unless the stack trace is
lying to us?

cd is pointing for some reason to an object not allocated. This would mean
that kzalloc returns such an object(?). Theoretically one could free a
statically allocated object using kmem_cache_free() and it would be put on
thefreelist. Then it could be returned from kzalloc (all only if debuging
is off)... so

Could you boot with full debugging?

Either switch on

CONFIG_SLUB_DEBUG_ON

or pass

	slub_debug

on the kernel command line.

Looks like percpu data is corrupted. One of my earlier fixes dimensioned
the kmem_cache_cpu array correctly. That is missing here.

Combined fix:

Ah, that was pilot error on my part. I didn't realize that the
second patch you sent was to be in combination with the first.
Sorry about that.

Yup, the two together finally got it.

Difficult since I also did not track how this belonged together. Sorry.


From: Christoph Lameter <cl@linux-foundation.org>
Subject: [SLUB] dma kmalloc handling fixes

1. We need kmalloc_percpu for all of the now extended kmalloc caches
   array not just for each shift value.

2. init_kmem_cache_nodes() must assume node 0 locality for statically
   allocated dma kmem_cache structures even after boot is complete.

No prob.

Replying and cc'ing so akpm sees this as our final answer. :)

Well I think this is going through the git tree for slab allocators via
