Greg,
Thanks for responding and excuse me for the delay in reply.
# This is a re-post as I had email server configuration issue.
# Excuse me if you receive similar messages twice.
I was finally able to stop the machine, and took out 1 of 3 drives
in question. I re-tested the drive, and the issue reproduced 100%.
Here's the model/serial code of the drive:
# output from "scsiinfo -a /dev/sda"
Vendor: ATA
Product: Hitachi HDP72505
Revision level: GM4O
Serial Number ' GEB531RE0GEPGB'
From the information I have gathered, this issue seems to be
either environment or usage-dependent. It seems it always reproduces,
or never happens. While I see many reports (and reports of "-1" fix
working) on various blogs/BBSs, I do also see many saying "doesn't
happen with me".
I must admit this weakens my proposal to apply the patch.
However, althrough it may not be 100% reproducible everywhere at
this time, I believe there is at least an ambiguity in the spec ("How
should ATA req on 0xfffffff be handled?") which could cause driver to
fail anytime, and so decided to submit a patch.
The fact *BSDs (and probably Intel) having similar fix also pushed
me to take action, and I'd also like to clarify that I'm not the
only one with this "-1" fix - the exact same stuff has been floating
on the net for months.
Now I have the drive at hand, I re-tested with latest 2.6.25.3
kernel (rebuilt from vanilla source, not some distribution kernel),
and here's the result:
# uname -a
Linux pc 2.6.25.3 #2 Thu May 15 01:05:14 JST 2008 i686 GNU/Linux
# dd if=/dev/sda bs=512 count=1 skip=268435455
dd: reading `/dev/sda': Input/output error
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.289322 s, 0.0 kB/s
# dmesg -c

ata3.00: error: { ABRT }
ata3.00: configured for UDMA/33
ata3: EH complete
...[same messages repeating several times]...
And for block size of 1KB-8KB, I get exactly the same error:
# dd if=/dev/sda bs=1024 count=1 skip=134217727
dd: reading `/dev/sda': Input/output error
# dd if=/dev/sda bs=2048 count=1 skip=67108863
dd: reading `/dev/sda': Input/output error

dd: reading `/dev/sda': Input/output error
# dd if=/dev/sda bs=16384 count=1 skip=8388607
dd: reading `/dev/sda': Input/output error
Now, here's more interesting behavior of the drive.
With enough "backoff" from the border, the drive responds
normally to the request:
# dd if=/dev/sda bs=4096 count=1 skip=33554431
dd: reading `/dev/sda': Input/output error
0+0 records in
0+0 records out

And the same test with 512-byte block request:
# dd if=/dev/sda bs=512 count=1 skip=268435455
dd: reading `/dev/sda': Input/output error
0+0 records in

I'm starting to see some pattern here...
So even if request goes over LBA address of 0xfffffff, it seems
it won't break if certain amount of request (8KB>) is sent prior
to accessing the border.
I have attached full log of the test (pctest.sh, pctest.log), so
please check it out if there's anything unclear with above excerpt.
Also, as this could be some hardware and/or software combination issue,
reports generated by lshw(1) and scsiinfo(1) are also attached.
Is there any other tests I can do to track down the issue?
Maybe sending raw LBA28 request directly to the drive may help to
identify the issue?
