Description Alar Suija 2004-06-11 12:08:21 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510

Description of problem:
My system-
PII 350, 256 MB RAM, mostly IDE, but using Adaptec SCSI2 adapter
2906(?) for scanner (Epson GT-7000) and internal HP CD Writer 9200+

Setup works perfect with Fedora Core 1 and *after boot* if using FC2.

But some time later (probably when scanner going to standby- circa
after 2-3 hours) every access to SCSI subsystem ends with hard crash.
(inserting flash disk or USB external HD or mounting CDROM using SCSI
device or start SANE etc etc) 

Version-Release number of selected component (if applicable):
kernel-2.6.5-1.358

How reproducible:
Always

Steps to Reproduce:
1. Start up system
2. wait :)
3. access to SCSI subsystem
    

Actual Results:  After 20 .. 30 second system freezes. using dmesg i
can see kernel emergency messages (and syslog works too)

Expected Results:  All works OK.

Additional info:

[al@riffle al]$ cat /proc/scsi/scsi

Comment 3 Dave Jones 2005-04-16 04:59:02 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.
