Description Achim Leubner 2003-10-07 14:04:35 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Description of problem:
On a dual processor machine with Intel Integrated RAID controller using Red 
Hat Enterprise 3.0 Public Beta with the "gdth" module loaded, I get 
segmentation fault during:
1. Shutdown/halt or "rmmod gdth"(basically calling gdth_flush())
2. Accessing the "gdth" information from the /proc filesystem, with 
say "cat /proc/scsi/gdth/0".

The problem was already reported in bug #66867, but it occurs again in this 
kernel version.


Version-Release number of selected component (if applicable):
kernel-2.4.21-1.1931.2.399.entsmp

How reproducible:
Always

Steps to Reproduce:
1. Install operating system with an Intel Integrated RAID controller
2. Access controller information from /proc, i.e. "cat /proc/scsi/gdth/0".
3.
    

Actual Results:  Kernel OOPS.

Expected Results:  Displaying controller information.

Additional info:

It's a problem in scsi_get_host_dev(). See bug #66867 for a detailed 
description.
