I have tested this patch:

http://user.it.uu.se/~mikpe/linux/patches/2.6/OLD/2.6.28/patch-sata_promise-reset-updates-v1-2.6.28

on a 2.6.31 kernel.

It continues with the same errors as:
{ DRDY ERR },
{ ICRC ABRT },
exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4,
link is slow to respond,
gradually reducing UDMA/133 to UDMA/33,
etc.,
with no apparent improvement.

One thing of note is that it happens always on one drive, and not ever
on the other.

It never happens on happens on ST3500641AS Seagate esata 500GB.
It always happens on  WD My Book esata 500GB.

I tried exchanging cables, and even reversing ports
(including with fstab tweak from sda to sdb) to rule out the cable
or the the controller port.
I tried copying data the other way around and the WD still gave one
group of errors, but writing triggers many more errors than reading.

The problem follows the drive.
The drive passes WD diagnostics and apparently functions fine except
for the messages. The WD drive is a second RMA replacement for same model
which gave same messages and I thought it was a problem.

On kernel 2.6.18.8, the throughput to the WD drive is a little faster
and the messages, which happen with the same frequency, are gentler.

hdparm in case there is some clue:

hdparm -I /dev/sda
