Description of problem:
When trying to write large file to SCSI disk controlled by aic7xxx
driver, it resets/aborts several times, then dumps state and offlines
the device. Filesystem module (reiserfs) then complains about not
being able to write journal.

Version-Release number of selected component (if applicable):
kernel-2.6.3-1.100

How reproducible:
Didn't try second time

Steps to Reproduce:
1. mv kernel-source-2.6.3-1.100-i386.rpm <filesystem-on-SCSI>
2. watch /var/log/messages


Actual Results:  Feb 24 22:50:32 pavelp kernel: scsi0:0:2:0:

Comment 2 Pavel Polischouk 2004-02-25 16:11:13 UTC 
this might be related to bug 115703
Comment 3 Pavel Polischouk 2004-03-09 17:40:36 UTC 
Same happens with kernel-2.6.3-1.100
This time no heavy activity was done - the failure happened when
trying to umount the filesystem as part of shutdown sequence. Messages
were almost identical to those reported before.
Comment 4 Pavel Polischouk 2004-03-14 01:39:38 UTC 
Re-confirmed for 2.6.3-2.1.253. No heavy activity is needed for the
driver to fail, only an attempt to read directory.

aic7xxx_old works fine with the same kernel - could be something as
simple as compile-time mis-configuration of aic7xxx (new) module.
Comment 5 Pavel Polischouk 2004-03-16 15:22:50 UTC 
This is a known problem, the patch exists in -mm tree:

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.4/2.6.4-mm2/broken-out/aic7xxx-deadlock-fix.patch

Please apply to RPM build pending inclusion to Linus tree. The patch
completely fixes this problem.
Comment 6 Dave Jones 2004-12-07 06:41:34 UTC 
fixed in the current errata kernel ?
Comment 7 Dave Jones 2005-04-16 05:08:40 UTC 
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat.  The Fedora legacy project will be producing further kernel
updates for security problems only.

If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.

Thank you.
