I'm seeing the same sort of failure with a pair of these same drives:
[ 3.570733] ata3.00: ATA-8: ST2000DL003-9VT166, CC32, max UDMA/133
wired into a rather old (2007ish) motherboard:
http://www.intel.com/p/pt_BR/support/highlights/dsktpboards/dg31pr
Base Board Information
Manufacturer: Intel Corporation
Product Name: DG31PR
Version: AAD97573-203
Serial Number: BTPR741000Y3
BIOS Information
Vendor: Intel Corp.
Version: PRG3110H.86A.0071.2010.0318.1704
Release Date: 03/18/2010
I've upgraded the BIOS in the motherboard and it didn't fix the issue
(nor were any SATA interop fixes listed in the BIOS ChangeLog). I had
also replaced the power supply and both cables before that.
I encountered these problems running an amd64 2.6.35-28 Ubuntu kernel
(the current Maverick kernel). I just upgraded yesterday to the Natty
kernel, which is 2.6.38-8 to see if it addressed the problem, and I
haven't seen it occur since, but given that this bug report reports it's
happening in Debian's 2.6.38-8, I'm not very hopeful.
I think this is probably something broken in either the drives or in the
drive-to-motherboard interaction. In looking at the motherboards which
are appearing here:
Gigabyte P35-DS3R
Supermicro X7SPA-H
All these boards are specified as supporting SATA 3.0Bps, but at least
mine and the P35-DS3R are pretty old; I'm not sure about the Supermicro.
So I am thinking there may just be a motherboard interoperability issue.
If this kernel upgrade doesn't address the problem, then I'm considering
replacing one drive at a time, and then the motherboard. (I would switch
drive vendor but it won't be easy to get a refund, so I'm willing to
give this a bit more effort.)
