This is similar to other reports, so I suggest adding it to the blacklist:

        { "ST380011AS",         "3.00",         ATA_HORKAGE_NONCQ, },

(haven't checked yet if it works)

When you have done so, please send a tested patch to

Jeff Garzik <jeff@garzik.org>
Andrew Morton <akpm@linux-foundation.org>
linux-ide@vger.kernel.org

thanks.

Comment 2 Jeff Garzik 2007-11-08 11:20:48 UTC
A timeout tells us nothing, sorta like this bug report :)  There is definitely -zero- information implying that this should be added to an NCQ blacklist.

Furthermore, on hardware like Intel ICH, a timeout is the only way we have to know that a DMA error occurred (it only sends an interrupt on success; assumes OS will notice failure via timeout).

It always recovers from the timeout, so I don't see any problem here.

Of course, a full dmesg and lspci might shed additional light.
Comment 3 Tejun Heo 2007-11-08 17:40:57 UTC
The driver is complaining about missing CLO support, so the controller seems to be a non-intel variant of ahci, or if an intel one, a pretty early one.

Anyways, mostly likely cause is hardware issues.

* Does 'smartctl -a /dev/sdX' indicate any problem?

* Perform common hardware debugging - swap / reseat cables, connect harddrive to separate power supply, etc.
Comment 4 Hans-Joachim Baader 2007-11-09 10:31:54 UTC
We have several of these machines, only the two with new ATA drivers make problems. The others run a 2.6.13.5 kernel.

smartctl doesn't indicate problems.

Comment 8 Tejun Heo 2007-11-12 06:20:31 UTC
I see, it's a ICH6.  It could be that the cause is the ICH6 not the drive.  Can you please connect another NCQ capable drive to the controller and see if the same problem occurs?  Or even better, connect ST380011AS to another NCQ capable controller and see whether it works.

If ICH6 AHCI turns out to be the culprit, we'll need to turn off NCQ support for the controller not the drive.

Thanks.

Hans,
Any update on this, Have you been able to try recommended in #8?
Comment 10 Hans-Joachim Baader 2008-02-08 02:59:14 UTC
I'm sorry, I didn't have the right hardware combination for further tests. I'll try to find some next week.
