See http://ata.wiki.kernel.org/index.php/Libata_error_messages for an 
introduction.

In general, tons of ATA bus errors and SError register bits means that 
problems are coming from the ATA bus, a.k.a. the SATA cable and its 
related connections.

So...  suspect bad cables, bad port connectors, cable interference, 
motherboard-caused interference or grounding problems, power supply 
problems.

hmm, or something totally odd...

what happens if you do: (after you made a backup!)
"dd if=/dev/sdX(where X is your affected hdd?) of=/dev/null bs=1"
Note:
The important bit is the small bs (blocksize) number.
You can throw in a O_DIRECT flag to disable the caches, or 
if you have some "empty" partition space, you can "dd" into
it with a small blocksize too)

my seagate & even a samsung hd103uj doesn't like that and will spew
out the same sort problems you have just posted... (but they work fine,
if I don't do nasty dd things!)

and unfortunatly my md(raid1) seems to do lots of "small" reads & writes
when it starts to check/resync the whole 1TB array :-/.

I did exchange power supply and I did exchange hard drives. The same
hard drive with the same cable works with SB600 and produces errors with
JMB363. So looks like it is not cable or hard drive problem. May be the
problem is JMB363 port connector on the motherboard. How can I check it?

Try new motherboard of same brand and model :/

In general, tons of ATA bus errors and SError complaints indicate some 
sort of problem at the physical layer/level.  Its always possible that 
software is to blame, but bug report patterns so far tend to point to 
hardware.

Hi!

I have a JMB363 myself and it has its share of problems.
I would say it is buggy hardware. (why would they otherwise
release a new windows driver every week ? if not to workaround
bugs in HW ;-)

My WD MyBook Studio Edition 500 GB external eSATA drive does not
work on the JMB363 correctly no matter what I try. Both
under linux and windows. I think the best was 30 minutes of
(apparent) error free operation under windows.

If interested, I can supply logs, data etc.
(I have a bunch of drives to try).

Regards,
David

Well, it is probably right time to try to get replacement motherboard
from store.

I think I got indirect confirmation of possible motherboard defect.
There are 2 sata ports managed by JMB363: GSATAII-1 and  GSATAII-2. I
found out that kernel errors appear only if I use GSATAII-1. If I
connect my drive to the GSATAII-2, there are no errors anymore.

Also, Seagate testing utility Seatools for DOS 2.07PG (bootable iso) is
hanging at startup even without connected sata drive, which also
indicates some motherboard problem (or again, utility problem). Seagate
support does not tell anything except something like "it should work"...

Thanks everybody for support.

I just got this* link from WD support, accompanied with the text:
"This sounds like an incompatibility perhaps with the ESATA controller.
Please see the link below for tested ESATA controllers."

Well, FWIW, JMB ahci's are one of my favorites and usually very well
behaved.

This one is being discussed both with JMB and WD.  It seems the bridge
chip used in the WD external drives is somehow incompatible with the
JMB ahci's.  Don't know whose fault it is or how it can be worked
around yet.  The issue is being tracked in the following bugzilla.

Somehow I've been confusing people a lot lately.  I asked my AMD contact
 a few times about sata_nv problems somehow thinking AMD acquired NVidia
instead of ATI.  :-)

I got a replacement motherboard. And I got absolutely same errors and

FWIW I have an MSI (P45 Neo2) mobo with JMB363 (only PATA connected)
and its second AHCI port (ata8, not connected) gives me the following.

The 2.6.26.2 kernel doesn't see any problem:

Linux version 2.6.26.2 (gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) SMP

...

.config differences which could somehow be relevant(?):

-CONFIG_GART_IOMMU=y
-CONFIG_K8_NB=y
-CONFIG_AGP_AMD64=y

(I'm using SWIOTLB in both cases, it's P45/Core2 duo based machine).

Can't see anything between 2.6.26.2 and 2.6.26.3 which could cause
that. Perhaps I should bisect it anyway?
For now I have just disabled these AHCI devices, didn't know that it
was ok with 2.6.26.2 (just noticed it in the logs). Will look at it.
