debian-user:

I have a new machine with debian-6.0.5-amd64 and:

Intel i7-2600S processor
Intel DQ67SW motherboard
Intel 520 Series 60 GB SSD


I noticed error messages similar to the following example on the console:

[ 131.742744] ata3.00: exception Emask 0x10 SAct 0x0 SErr
0x400100 action 0x6 frozen
[ 131.742787] ata3.00: irq_stat 0x08000000, interface fatal error
[ 131.742806] ata3: SError: { UnrecovData Handshk }
[ 131.742822] ata3.00: failed command: WRITE DMA EXT
[ 131.742839] ata3.00: cmd 35/00:00:c8:ce:79/00:04:00:00:00/e0
tag 0 dma 524288 out
[ 131.742840] res 50/00:00:c8:ca:79/00:00:04:00:00/e0
Emask 0x10 (ATA bus error)
[ 131.742886] ata3.00: status: { DRDY }


I assume these are error messages coming from the disk device driver
(?). What do they mean?


I then upgraded the kernel to 3.2.0-0.bpo.2-amd64 via debian-backports,
and the errors filled the console whenever the disk was busy (such as
running tasksel and installing Graphical desktop environment).


STFW, I installed sysfsutils and added the following entries to
/etc/sysfs.conf. The quantity of messages decreased:

block/sda/device/queue_depth=1
block/sdb/device/queue_depth=1


Any suggestions?


TIA,

David

Mmm... given that the system is new (is a DIY or you bought the system
already assembled)? it can be a bad or poor sata cable or loose
connection. I'd first try to replace it and see how it goes.

It can be something coming from the kernel or a hardware problem. I'd
first locate the offending device and replace the SATA cable (always
use good quality cables and discard the ones coming with the motherboard).

dmesg | grep "ata3.00" will tell what's attached to the SATA 3 port.

Kernels hackers can tell you some tips (parameters) you can try to pass to
the kernel line, let's hope they are landing around here :-)

When you say "discard" here, do you mean toss them out in the rubbish?

According to this wiki
http://lime-technology.com/wiki/index.php/The_Analysis_of_Drive_Issues#Drive_Interface_Issues

it could be a number of things, including:

# inadequate power supply
# device and controller don't like each other on 3Gbps
# cable too long or flaky connector (especially with eSATA cables or
genders or backplanes)
# faulty controller or drive

etc...

Something similar happened to me and I went out and bought another
machine. I've still got the failing (ed) one (which eventually would not boot at
all, especially after I kind of took it apart and maybe didn't put it
back together correctly ;-)), but I'm still planning on replacing
the internal sata cables to see if that does the trick.

If the new machine is under warranty, maybe you can get the shop you
bought it from to fix it, if you indeed bought it from a shop at all.

Good luck.

No, I mean "put them into the drawer" and reserve for another things
(hardware testing or emergency situations).

I bought parts and put them together.

The Intel 520 SSD.

I was using a StarTech SATDOCK2520 mobile dock. I swapped cables and
the problems persisted. I installed the SSD internally and the problems
went away. :-)


Thanks!
