Re: Is this an SSD problem or a controller problem?
The analysis done by Jeremy is probably right. The device return errors in
response to commands disabling capability that it reported as suppoted and
enabled. That is not fatal, but just annoying. Send me please output of the
'camcontrol identify ada15 -v' to check.
In case of smartctl I guess there is some more problem causing command
timeout and following device reinitialization with the same errors. That
may already be fixed in 9-stable branch.

It is neither an SSD problem nor a controller problem.
FreeBSD is issuing a specific ATA CDB command to the SSD, and the SSD
rejects this request, returning ABRT status. This is perfectly normal
per ATA specification; the error is harmless.
You should open a PR on this matter, as FreeBSD should be adjusted in
some manner to deal with this situation, either via appropriate
workarounds or a drive quirk. mav@ would know what's best.
You will need to provide output from the following commands in your PR:
* dmesg
* camcontrol identify ada15
* pciconf -lvcb
* Same lines you did in your Email
Further technical details, which you can put into the PR if you want:
Looking at src/sys/cam/ata/ata_all.c we can see that the output of the
ACB is in bytes, output per ata_cmd_string(). Thus:
ACB: ef 90 00 00 00 40 00 00 00 00 02 00
Decoding per T13/2015-D rev 3 (ATA8-ACS2) working draft spec:
0xef = command = SET FEATURES
0x90 = features = Disable use of SATA feature
0x00 0x00 0x00 = lba_*= n/a
0x40 = device = n/a
0x00 0x00 0x00 = lba_*_exp= n/a
0x00 = features_exp = n/a
0x02 = sector_count = Enable/Disable DMA Setup FIS
Auto-Activate Optimisation
0x00 = sector_count_exp = n/a
DMA Setup FIS is defined as:
7.50.16.3 Enable/Disable DMA Setup FIS Auto-Activate Optimization
A Count field value of 02h is used to enable or disable DMA Setup FIS
Auto-Activate optimization. See SATA 2.6 for more information. The
enable/disable state for the auto-activate optimization shall be
preserved across software reset. The enable/disable state for the
auto-activate optimization shall be reset to its default state upon
COMRESET.
This feature has to do with NCQ capability for certain types of DMA
transfers.
src/sys/cam/ata/ata_xpt.c contains the responsible code. I could be
wrong here (mav@ please correct me), but in probestart(), there is:
452 case PROBE_SETDMAAA:
453 cam_fill_ataio(ataio,
454 1,
455 probedone,
456 CAM_DIR_NONE,
457 0,
458 NULL,
459 0,
460 30*1000);
461 ata_28bit_cmd(ataio, ATA_SETFEATURES,
462 (softc-caps CTS_SATA_CAPS_H_DMAAA) ? 0x10 :
0x90,
463 0, 0x02);
464 break;
CTS_SATA_CAPS_H_DMAAA is defined per include/cam/cam_ccb.h as
Auto-activation, and its name implies DMA, so this would match the
feature in question.
This would explain why you see it when the machine boots (xpt(4) probe),
as well as when smartctl is run or smartd starts (uses xpt(4)).
However, I noticed this piece of code in probedone():
739 /*
740 * Some HP SATA disks report supported DMA
Auto-Activation,
741 * but return ABORT on attempt to enable it.
742 */
743 } else if (softc-action == PROBE_SETDMAAA
744 status == CAM_ATA_STATUS_ERROR) {
745 goto noerror;
Which makes me scratch my head -- the comment and logic seems to imply
there shouldn't be any error condition reported, but you do see one.
This also implies that the drive advertises per SATA protocol DMA AA yet
when xpt(4) tries to disable it the drive rejects that request with ABRT.
I don't know why OCZ rejects disabling that feature, but whatever.
Addendum note for mav@ -- we also need to add an ADA_Q_4K quirk entry to
ata_da.c for Vertex 4 SSDs (OCZ-VERTEX4).
