Hi,
I just tested 2.6.16-rc5 kernel on MSI 9136 dual Xeon server
motherboard with 16 GB of memory and the kernel detects only 8 GB of
RAM instead. 2.6.15 kernel detected properly 16 GB. I haven't tested
any kernel revisions in between these two, but could if you point me
in a specific direction. Attaching diff(1) output of dmesg(1) outputs.
Please Cc: me in replies. Thanks!
Martin

These numbers are what the BIOS is telling the kernel about your machine.
Was the BIOS changed?
If not, you might need to wiggle those DIMMs or something.

No, it hasn't since we got the motherboard. Yes, it is 1.20 instead
of 1.50. The MSI web is such a crap I couldn't first of all get the
file at all and once found on a local reseller's page the zip file
contains no Changelog, so I have no clue what happened between 1.20
and 1.50 BIOS revision.

It is really something else, 16GB can be seen under 2.6.15,
2.6.15-rc1 (if I remember right my previous kernel version).
I can reproduce just by booting with "wrong" kernel version.
Any other recommendation? Except flashing and praying?
I haven't touched the BIOS setting either, I worked completely remotely.

BTW, BIOS during the POST test shows all 16GB, it is only
linux-2.6.16-rc5 who get's it wrong. Even the summary window
provided by BIOS just before grub gets loaded shows 16GB of RAM.
I don't believe it is anything else then the kernel.

Are you sure that it was 2.6.15 which found the full 16G?
Because there was a change which could have affected this. But it was
merged in late October and was present in 2.6.15.
You could try a `patch -p1 -R < this:'

[PATCH] fixup bogus e820 entry with mem=
This was reported because someone was getting oopses reading /proc/iomem.
It was tracked down to a zero-sized 'struct resource' entry which was
located right at 4GB.
You need two conditions to hit this bug: a BIOS E820_RAM area starting at
exactly the boundary where you specify mem= (to get a zero-sized entry),
and for the legacy_init_iomem_resources() loop to skip that resource (which
only happens at exactly 4G).
I think the killing zero-sized e820 entry is the easiest way to fix this.

It certainly is possible that my patch caused the bug. However, my
patch only affects limit_regions(), which is only called when the user
specifies a mem= argument on the command-line. When they do this, in
addition to the BIOS-e820 printout, they should also see a "user-defined
physical RAM map:", which I don't see in the diff. Also, I'm pretty
sure that this e820 printout runs before parse_cmdline_early(), where
limit_regions() is called.
Martin, in any case, I have debugged things in that code recently, and
I'd be happy to help you fix your problem. I've attached a patch that
does a ton of e820 debug printks. If you could get me a full copy of
your dmesg with that applied, I should be able to locate the problem a
bit more quickly.

Hi Dave,
thanks for answer, the dmesg output is attached. I haven't tried
reverting your patch as suggested by Andrew yet. Would do tommorow
if still desired.

So when the machine claims to have only 12GB of RAM, I see with lshw(1):
*-bank:6
description: DIMM DDR Synchronous 266 MHz (3.8 ns) [empty]
product: CM75SD2048RLP-3200
vendor:
physical id: 6
serial: 00000000
slot: DIMM 7
clock: 266MHz (3.7594ns)
*-bank:7
description: DIMM DDR Synchronous 266 MHz (3.8 ns) [empty]
product: CM75SD2048RLP-3200
vendor:
physical id: 7
serial: 00000000
slot: DIMM 8
clock: 266MHz (3.7594ns)
I am only curious why the product: field is not empty but rather
shows type of the actual module. All eight DIMMS are same Corsair
2GB RAM modules (sorry, I think I wrote Kingston previously but is
not true). Moreover, the modules are at 266MHz and not on 333MHz,
the board would take only 6 modules at 333MHz. So lshw should report
-2700 instead of -3200. Inspecting their serial numbers in the
invoice I see:
340540434
340540435
330541284
330541283
330541282
330541281
330541280
330541279
Yes, 2 are different. I guess your question would be whether those 2
unseen DIMMS are the first two serial numbers ... I can't say now
but definitely when only 8 GB of RAM are detected the problem would
include additional two DIMMs.
So, what would you recommend now. To flash from BIOS 1.20 to 1.50
and pray? ;-)
Martin

copy_e820_map() is really the first place that the kernel sees what the
BIOS has put in the e820 map. Since something is wrong _this_ early, I
really have to point the finger at the hardware again. It simply didn't
tell Linux that there was RAM there.

If it were hardware from a large vendor, I'd probably call support and
get them to ship me new parts. :)
Other than the BIOS update, there's not a whole lot you can do other
than move the DIMMS around and hope they prefer certain slots to others.
