Hello,

I was asked to CC this list regarding an NCQ issue I'm having with many WD400YR-01PLB0 drives.

I have ~400 WD400YR-01PLB0 drives and some have NCQ errors that temporarily lock drive (and system) until the operation times out.  They look exactly the same in hdparm (same model, firmware version, etc), but there is a sticker on the back of the drive that we believe is a WDC internal version number.  100% of the drives that have AD on the end of the sticker have the problem and 100% of the ones that have AJ (or later) do not.  They all came from different batches and manufacturing locations so we're assuming it was some sort of silent revision.  This does not appear to be the same problem as the spurious NCQ issue thta Tejun fixed in December.

The sticker for a few drives that have the errors:
2061-701310-C00 AD	XS 2R19 2Q3v 1 0006340 6346
2061-701310-C00 AD	XS 2R19 2H28 4 0005330 6335
2061-701310-C00 AD	XS 2R19 1YSS 1 0002330 6332
2061-701310-C00 AD	XW 2R19 5JMQ 1 0005290 6295

The sticker for those that work correctly:
2061-701310-C00 AJ	XS 2R26 12JP 5 0007510 6517
2061-701310-C00 AJ	XS 2R26 0JPY 1 000145R 6451
2061-701310-C00 AJ	XS 2R26 12HQ 5 0007510 6517
2061-701310-C00 AK	XS 2R27 0FM6 4 0001140 7141

This sticker is on the underside of the drive on the plastic on the side of the drive with the legacy power connector



This is the output from hdparm -I, as well as uname -a.  All the drives look exactly the same in hdparm -I, so I'm not going to post more than one.

These are a sample of the NCQ issues in dmesg and /var/log/messages.  It appears to be a blocking call so the system locks up for sometimes up to an hour.  To get the errors to occur I need to be doing heavy drive writing for a period of more than a few minutes.

I suppose you're talking about the spurious completion thing, right?

Hmmm... okay.

Ah.. ADMA.  There were some recent fixes but AFAIK there still are
remaining issues with ADMA support.  It's best to cc Robert Hancock
<hancockr@shaw.ca> who is maintaining sata_nv.

Thanks.

They look exactly the same in hdparm (same model, firmware version, etc), but there is a sticker on the back of the drive that we believe is a WDC internal version number.  100% of the drives that have AD on the end of the sticker have the problem and 100% of the ones that have AJ (or later) do not.  They all came from different batches and manufacturing locations so we're assuming it was some sort of silent revision.  This does not appear to be the same problem as the spurious NCQ issue thta Tejun fixed in December.

I don't think the driver is to blame for this one. CPB resp_flags of 2 
indicates the controller says that tag is "released", i.e. drive has 
been given the command but not completed. If it's timing out in that 
state, either the NCQ implementation is bad enough that it allows 
certain queued commands to starve for over 30 seconds, or the drive is 
just forgetting about them entirely.

Unfortunately, if the firmware revision does indeed appear the same on 
both sets of drives, the only automated way we could likely address the 
problem would be to blacklist NCQ on all of those drives of that 
model/revision..

Hmm... it's weird that this problem hasn't been reported on other
controllers.  Lanstein, can you be persuaded into trying out another NCQ
capable controller?
