> Attached the boot log and config file.

Kamelesh,

I don't see anything obvious in the boot_log.

I used your "dotconfig" file to build a 2.6.23-rc3-mm1 kernel
and booted it on my test system ... it worked just fine
(except that for some reason the network did not come up :-( )

I tried to compare my boot log with yours ... you have some
different devices (E.g. your ethernet links are Tigon3 while
mine are e1000) ... so the memory leak in a driver theory
is a possibility.

Try adding a dump_stack() call to lib/swiotlb.c where the
"DMA: Out of SW-IOMMU space ..." message is printed.  That
would tell us who is making the call that fails (they
might be an innocent bystander after someone else has
used all the space ... but this is unlikely).

Hmmm!  So you were in the mpt/fusion driver when you ran out
of SWIOTLB space.  That's an area where we both have the same
hardware ... and since it booted for me, it means that the
driver isn't totally broken.

I'm totally ignorant of what goes on inside this driver though.
You have more "ioc's" than I do.  I only see messages from mpt
bringing up ioc0 & ioc1.  Your boot_log also has ioc2 (which is
where you crash).  Here's the sdiff(1) output comparing the MPT
part of your boot log with my successful boot of the same kernel
and config (your log is the one on the left).  Maybe some MPT/Fusion
expert can spot something important in this bit?

The more ioc's you have, the more space you will use.

Default SW IOTLB allocation is 64MB ... how much should we see
used per ioc?

Kamelesh: You could try increasing the amount of sw iotlb space
available by booting with a swiotlb\x131072 argument (argument
value is the number of 2K slabs to allocate ... 131072 would
give you four times as much space as the default allocation).

Hmm.  Must be something else going on then.  It should be less than 1MB
per ioc plus whatever is used for streaming I/O.

I traced the pci_alloc_consistent calls from PrimeIocFifos on my
system.  There are two calls for each ioc.  The first is for
266368 bytes, the second for 16320 bytes.

I wonder why Kamalesh's system wants the slightly different
amount (263200 bytes) from what my system asks for?

It also looks to be a little unfriendly to swiotlb to ask for
more than 256K at a time (see IO_TLB_SEGSIZE) in swiotlb.c

I believe those would vary a bit based on the exact firmware
rev and perhaps nvram settings.  Also driver settings, but
those are presumably the same.

Actually, you can see that you have a different chip rev level and different
firmware revs, so that's probably why the requested sizes are a little
different.

Compare /proc/mpt/ioc0/info if you're curious.  There's probably a small
difference.

I saw same trouble on my box, and I chased what was wrong.
Here is today's progress of mine.

__get_free_pages() of swiotlb_alloc_coherent() fails in rc3-mm1.
(See following patch)
But, it doesn't fail on rc2-mm2, and kernel can boot up.

Hmmm....

That looks to be part of the problem here ... failing an order=3
allocation during boot on a system that just a few lines earlier
in the boot log reported "Memory: 37474000k/37680640k available"
looks bad ... but perhaps having *more* memory is part of your problem.
You may have run low on GFP_DMA memory because some allocation
scaled by memory size has chewed up a lot of your memory.  To check
this try booting with a "mem=4G" parameter and see if that helps
you.

But it is also bad that the swiotlb() code failed to handle this.
Can you check whether the problem is related to the size of the
allocation being just over 256K (a magic number for swiotlb since
IO_TLB_SEGSIZE is 128 times a slab size of 2k).  Try changing
lib/swiotlb.c to set IO_TLB_SEGSIZE to 256 instead.

Others are reporting machines which fail int he memory allcoator much
earlier, and which claim to have four CPUs and 16 nodes.  So something is
very wonky in the rc3-mm1 page allocator.

I guess suspicion has to be directed at the memoryless-nodes patches, but
until that's cleared up I don't think there's much to be gained from
chasing this iommu problem, now that you've worked out that it's a bogus
memory allocation failure (thanks).

I found find_next_best_node() was wrong.
I confirmed boot up by the following patch.
Mel-san, Kamalesh-san, could you try this?

This boots the IA-64 successful and gets rid of that DMA corrupts
memory message. As a bonus, it fixes up the memoryless nodes (the bug
where Total pages = 0 and there is a BUG in page_alloc.c) by building
zonelists properly. The machine still fails to boot with the more familiar
net/core/skbuff.c:95 but that is a separate problem.

Well spotted Yasunori-san.

Andrew, this fixes a real problem and should be considered a fix to
memoryless-nodes-fixup-uses-of-node_online_map-in-generic-code.patch unless
Christoph Lameter objects.

I reworked that patch and posted the update on 16aug which does not have
this problem:

http://marc.info/?l=linux-mm&m\x118729871101418&w=4

This should replace

Sure.  Here it is.  This looks nicer to me than explicitly skipping
unpopulated nodes in find_next_best_node()--as I tried to do, but
botched it :-(.  I didn't notice that because I'd moved on to v2 before
testing with any significant load.  Even when I was running with v1 with
botched zonelists, I apparently had sufficient memory on each node that
I never had to fallback.

I also didn't notice that Andrew had added v1 instead of v2 to the mm
tree.  Will pay more attention in the future, I promise.

---------------------------
PATCH Diffs between "Fix generic usage of node_online_map" V1 & V2

Against 2.6.23-rc3-mm1

V1 -> V2:
+ moved population of N_HIGH_MEMORY node state mask to
  free_area_init_nodes(), as this is called before we
  build zonelists.  So, we can use this mask in 
  find_next_best_node.  Still need to keep the duplicate
  code in early_calculate_totalpages() for zone movable
  setup.

mm/page_alloc.c:find_next_best_node()

	visit only nodes with memory [N_HIGH_MEMORY mask]
	looking for next best node for fallback zonelists.

mm/page_alloc.c:find_zone_movable_pfns_for_nodes()

	spread kernelcore over nodes with memory.

	This required calling early_calculate_totalpages()
	unconditionally, and populating N_HIGH_MEMORY node
	state therein from nodes in the early_node_map[].
	This duplicates the code in free_area_init_nodes(), but
	I don't want to depend on this copy if ZONE_MOVABLE 
	might go away, taking early_calculate_totalpages()
	with it.
