sil3114 data corruption

sil3114 data corruption

[Bernd Schubert]

[sorry for sending twice, but after I read the sil sources, I see the mail 
address had been wrong]

Hi,

somehow the sil3114 causes data corruption with some (newer?) disks. Simply 
filling the filesystem with zeros and reading the these data will make the 
kernel to report filesystem corruption. 
This is definitely not an issue of memory, since the systems (several tested) 
do have ECC memory and the memory is monitored with EDAC. 

Also not an issue of the filesystem, also several tested.

The ST3250820AS data on the ST3250820AS disk will suffer from data corruption, 
but the data on the older ST3200822AS will *not*.

kernel versions tested: 2.6.15-2.6.20

Any ideas how to proceed?

Thanks,
Bernd

Update: Setting sata_sil.slow_down=1 fill fix the problem, seems there are 
some drives missing in the quirk table.

Jeff, I found an old patch/workaround from you 
(http://uwsg.indiana.edu/hypermail/linux/kernel/0403.1/1957.html), can you 
give me any further information why this never went into the driver?

Thanks,
Bernd

I will send 3 mails with patches to fix this corruption.

[PATCH 1/3] Re: sil3114 data corruption

[Bernd Schubert]

This will add the Seagate ST3250820AS to the mod15 blacklist.

I think this is rather trivial and should go into any any release as soon as 
possible, since there will be data corruption without it for this disk.

Re: [PATCH 2/3] Re: sil3114 data corruption

[Bernd Schubert]

This will add the sil3114 back to the controllers with the mod15 bug. Without 
this patch no workaround for this controller is done and people might/will 
suffer from data corruption.

Also rather trivial, though with a huge effect, the speed for the effected 
disks will go down from about 45-50MB/s to 20-25MB/s. But better safe than 
lost data or damaged filesystem.

Re: [PATCH 3/3] faster workaround

[Bernd Schubert]

This is based on a patch from Jeff from 2004, but backported to 2.6.23 and 
furthermore, it will use the 7.5kiB/512B splitoff for blacklisted drives 
only.

Jeff, why did you replace ATA_SHT_USE_CLUSTERING and ATA_DMA_BOUNDARY?

Its probably better to simply make your own sil_qc_prep function for this
case rather than touch the core code.

If you are just fiddling with the way the data is split then
LIBATA_MAX_PRD - 1 should be totally safe)

And since in this approach we are merely splitting the last PRD entry in
some obscure cases we might as well do it by default as it should have no
performance impact of any note done this way.

Unfortunately all this stuff is quite meaningless, which was why my 
patch was never merged.

The problem is that the 3112 generates Data FIS's of a size other than a 
multiple of 512 bytes.  Spec-legal, but exposed firmware bugs in many 
early SATA drives.  Early Seagate hard drives choked when the formula 
(sector%15)==1 was satisfied (or something along those lines).

The problem with the fix is that Data FIS size is only roughly 
correlated to PRD segment length or DMA boundary -- the chip could 
decide to send out a frame even if the PRD length is < 8K.  The 3112 can 
generate not-512b-sized FIS's at any time, not just at the end of the 
transfer.

That leaves us with two observations:

1) Just about the only valid optimization is to ensure that only the 
write path must be limited to small chunks, not both read- and 
write-paths.  Tejun had a patch to do this a long time ago, but it's an 
open question whether the large amount of code is worth it for a rare 
combination.

2) Once we identified, over time, the set of drives affected by this 
3112 quirk (aka drives that didn't fully comply to SATA spec), the 
debugging of corruption cases largely shifted to the standard routine: 
update the BIOS, replace the cables/RAM/power/mainboard/slot/etc. to be 
certain of problem location.

How large? This patch is rather small? Where can I find it?

Replace this disk or the sata controller maybe, but usually people don't want 
to replace a big cluster, even if it is already 3 years old, this has to wait 
at least another 3 years.

The problem came up, when 200GB drives were replaced by *newer* 250GB drives 
(well maybe not the newest, no idea were they came from).

Anyway, I'm testing for more than 24h already and didn't observe any data 
corruption as without the patch. I know this is only an obersavation and no 
definite prove...
Also, this is with 3114, maybe this chip behaves a bit different than 3112?

Thanks,
Bernd

3114 + new SATA drive is definitely a new one for us.

It would help to (a) use the latest kernel, (b) post your .config with 
the latest kernel, (c) post lspci booted into latest kernel, and (d) 
post dmesg booted into latest kernel.

a) 2.6.23 + sil-patch I posted, this is on a customer system (though my former 
group), I wouldn't like to use -mm there.

b) .config is attached

c) attached

d) attached (don't get irritaded by those machine check events, thats "GART 
TLB errorr", harmless warnings, just not disabled in the bios).


Thanks,
Bernd

And the 3114 is the same ?

Except for the continued series of later SI + Nvidia chipset (mostly)
pattern which seems unanswered but also being later chips I assume
unrelated to this problem.

3114 should not be affected by this problem (see below).

Most likely we are led down this road because the 'slow_down' module 
parameter has an excellent capacity for hiding all manner of problems.

As a tangent from this thread, this is why I was OK with adding the 
libata.dma even for SATA.  Sometimes knobs are found useful by users, 
though perhaps not its original intended use.  Sometimes masking a 
hardware problem can help you get through the rest of your day on hold 
with vendor support :)

The SIL_FLAG_MOD15WRITE flag is set in sil_port_info[] is set according 
to the best info we have from SiI, which indicates that 3114 and 3512 do 
not have the same problem as the 3112.

I don't think this data corruption problem w/ sil3114 is related to
m15w.  m15w workaround slows down things quite a bit and is likely to
hide problems on PCI bus side.  There are reports of data corruption
with 3114 on nvidia (most common), via and now amd chipsets.  There's
one on intel too but IIRC wasn't too definite.

According to a user, freebsd didn't have data corruption problem on the
same hardware.  I copied PCI FIFO setup code (ours is broken BTW) but it
didn't fix the problem.

I'll try to reproduce the problem locally and hunt it down.

Thanks.

thanks for your help and please tell me, if I can do anything. We have this 
problem on a production system, but the node in question will be rebooted in 
Thursday (ups needs to be replaced). If there are some tests/reboots/whatever 
I could do, it would be best to do it shortly after the scheduled reboot.

Actually I now would have attempted to port your mod15 patch 
(http://home-tj.org/wiki/index.php/Sil_m15w#Patches) to 2.6.23, hoping it 
would solve Soerens problem and ours as well (ours magically already went 
away using the mod15 fix). Well, maybe I port it anyway to 2.6.23 to see if 
it also solves our problem.


Thanks,
Bernd

err wait, the motherboard I am having is also via based. however the
m15w workaround just slowed down everything but the problem still
appeared.

also to be sure that it is really some problem related to the particular
seagate drive vs. sil3114 I created a 200G file of zeros on one of the
known to work seagates. and indeed it was all zeros...
