Is there anything in these /var/log/messages excerpts from two
different hosts that can identify which (external) sata device is
connected with the reported errors? I don't see any connection
between that information and the content of
/dev/disk/[by-path,by-id]. Is there a way to tell if a kernel bug
or a device is the problem? These errors show up in conjunction
with various degrees of I/O delay, sometimes as bad as several
minutes of inability to get bash to respond to keyboard input. The
most recent time some commands would result in a simple
segfaulted. Others would produce bash: input/output error.
Ctrl-Alt-Del failed to reboot, as did init 6 (input/output error),
forcing me to use power switch and wait a seeming eternity for fsck
on 1TB+ partitions to complete.

You'll find that info earlier in the log. e.g. on my system:
[ 1.290219] ata1.00: ATA-8: OCZ-VERTEX2, 1.35, max UDMA/133

Alternatively, lsscsi -v will show:
[0:0:0:0] disk ATA OCZ-VERTEX2 1.35 /dev/sda
dir: /sys/bus/scsi/devices/0:0:0:0
[/sys/devices/pci0000:00/0000:00:11.0/ata1/host0/target0:0:0/0:0:0:0]

... where you can see the 'ata1' in the sysfs path.

The problem with that type of error is that it's tough to isolate what
the problem is without detailed hardware knowledge (the type of
knowledge I don't personally have).

Joey's team has more experience with ATA issues. Perhaps they can assist.

I've run the Seagate thorough diagnostics on the drives, 100% error
free.

The suspect device is
http://www.newegg.com/Product/Product.aspx?Item=N82E16817173042 but
I want to provide Rosewill tech support hard evidence of the
incompetence of the device if I can be sure it is exclusively
responsible for the errors. I bought 5 of them and never had
trouble. Only with #6, the only version 2 of the model I have, has
there been a problem. The #6 I have now is actually the 3rd
replacement of the original #6 purchased last September.
