Description Oliver Schulze L. 2003-04-25 22:27:28 UTC
Description of problem:
When I install RedHat 9 in a SCSI disk with a SCSI Adapter Adaptec 2940U,
I got this error in Alt+F4 console:
(SCSI0:A:6:0) parity error detected in Data-in phase. SEQADDR(0x1a2)

Is this a critical error message?

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install RH9 in a SCSI disk
Actual results:

Expected results:

Additional info:

Comment 1 Michael Fulbright 2003-04-28 19:02:32 UTC
Appears to be a message from the kernel, reassigning.

Comment 2 Oliver Schulze L. 2003-04-28 19:12:02 UTC
This problem ocurred when I was using 2 cp commands in background to copy data
from one disk to another. Something like this:
cp -a home usr /mnt/new &
cp -a var boot /mnt/new &
I was in rescue mode.

Later, I booted again in rescue mode and issue one cp command at a time and could
not see any error.

At this stage I don't have too many info about the error message nor how to
reproduce it. Maybe it was a problem with my SCSI adapter. I restored the
default settings in the SCSI BIOS before I tryied again.

Comment 3 Oliver Schulze L. 2003-04-29 06:00:15 UTC
Got more info.
I manage to upgrade a RH70 to RH9 and while working on the server I noted the
message again:
"kernel: (scsi:A:6:0): parity error detected in Status phase. SEQADDR(0x7f)

The SEQADDR change with this values: 0x9e, 0xa5, 0x82

The Adaptec card is: AHA-2940 U/UW/D AIC-7881U

The mobo is an ASUS P4S-533-MX running a Pentium 4 1700Mhz

Comment 4 Bugzilla owner 2004-09-30 15:40:50 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
