This is about the most significant line

The SCSIRATE indicates wide. I'd bet this is a narrow device; in which case, does
echo 0 > /sys/class/spi_transport/target0:0:3/max_wide
and then triggering a revalidate with
echo 1 > /sys/class/spi_transport/target0:0:3/revalidate
produce anything different?

Yes ... sorry should have looked instead of doing it from memory.

This should produce output in dmesg to indicate the device speeds were
rescanned.

Yes, all aic7xxx cards are wide capable

That's what the two echos do. The domain validation is supposed to
detect a narrow device on a wide cable, but it looks to be failing
somehow ... although we won't know this for definite until you try it on
the latest kernel.
The way to force narrow it to set it in the aic bios if you can. The
driver picks up that setting and places it in max_width.

Sorry for the previous HTML-formatted e-mails. This is now corrected.
The first thing to realize is that this system only has three devices on
the actual scsi bus to this adapter:
7 - adapter card
3 - Exabyte 1x10 autoloader
6 - Exabyte VXA-2 tape drive
I only need 20 Mbps since the maximum speed of the VXA-2 tape drive is 6
Mbps uncomressed or 12 Mbps compressed (estimated since depends on
compressibility). Looking at the backup reports I am getting very close
to 6 Mbps performance.
I looked at the bios settings for this device and it appears to be set
as near as possible to a narrow device:
1) The bios is entered by typing ctrl-A during the Adaptec bios output
console while booting. All 15 scsi IDs show up on the console. Each
device can be set separately.
2) The entries were initially set as follows:
sync transfer 20 Mbps, scsi IDs 0-7
a-sync transfer, scsi IDs 8-15
initiate wide negotiation - NO - 0-15
enable auto-disconnect - YES 0-15
send start to unit - YES 0-7, NO 8-15
enable write back cache - YES 0-7, NO 8-15
bios multiple LUN - NO - 0-15
include in bios scan - YES 0-7, NO 8-15
3) I also tried one change to these same entries (which is where it is
now):
sync transfer 20 Mbps, scsi IDs 0-15
enable auto-disconnect - NO 0-7, YES 8-15
4) I also tried booting with all devices in async mode, and it also
failed to find the media changer.
5) The narrow bus can be verified by the maximum sync transfer available
is 160 Mbps in wide setting and only 40 Mbps in the narrow setting.
6) A separate screen shows two entries
LVD/SE connector automatic
Fast/Ultra-SE connector automatic
These could be changed to enable or disable, but I left as automatic.
7) The bios version is 3.10.0 which is the latest available from Adaptec
and dated 30-May-2001.
8) I booted up under 2.6.18.8 and the old aic7xxx driver which is
working, and the 2.6.22.1 and the new aic7xxx driver which is not
working.
9) the output from the commands you asked for are shown below for the
2.6.22.1 kernel. They indicate parity errors on the changer at scsi
id=3. Also, when booting up under 2.6.18.8, the linux media changer
scsi device works and initializes; when booting up under 2.6.22.1, it
does not; probably because of the same parity errors ?

This is the problem.
Something in the transport class is causing WIDE to be set regardless of
the max_width setting ... this looks to be a bug in the aic7xxx
transport class implementation

Once it goes wide on a narrow device, you get immediate parity errors
half the time, because you're missing the upper 8 bits for the parity
calculation.
I'll see if I can trace this inside the driver ... naturally, I have no
aic7xxx setup where I only have a narrow device.

OK, could you try the attached as the fix ... I've verified a similar
problem on the aic79xx which this fixes ... I just don't have access to
an aic7xxx currently to try it out with, but I think it should work.

It was created against current git, but there should be little
difference in the aic driver between that and 2.6.22.1, so it should
apply there as well.

Yes, that should do it.

Try the attachment ... that usually defeats mailer text translations.
the md5sum just for integrity's sake is 9ba6ace80c06d34b5391407ea68c381a
I tested it against 2.6.22.1 and it applies (but with some offsets):

Thanks James. It patched this time, compiled, and is now rebooting. I
have a backup running tonight at 1am. I will report back in.
This would be great if it fixes it. I also have another similar bug
with the aic79xx driver on another machine (see my other bug reports).
I wonder if this will fix it also ?
