Description Matthias Kruspe 2001-05-13 18:42:14 EDT
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [de] (X11; U; Linux 2.4.2-2 i686)

Description of problem:
When I use the program ksysctrl and click at the Refresh button, the hard
disc activity raises very heavy. After that I get various messages about
damaged file systems. Can't reboot the system normally. Must do a hard
reset. After that i get kernel panics and cant mount the filesystems. The
partition table and a ms-windows-system at the same disc are also affected.
Maybe there is a bug in the scsi-interface. (I only use SCSI, no IDE)

How reproducible:

Steps to Reproduce:
1.start ksysctrl
2.click refresh

Actual Results:  heavy damage to the filesystem

Expected Results:  re-scanning the scsi-chain and refreshing the data shown

Comment 2 Bernhard Rosenkraenzer 2001-05-14 06:33:51 EDT
Looking at the ksysctrl code, I don't see any write accesses to the 
filesystem. Also, I can't reproduce this on my (IDE-only) system.

This must be a problem with SCSI (most likely with the low level driver for 
your controller; which controller are you using?) or with your hardware.

Assigning to kernel because that's where SCSI drivers reside.

Comment 3 Bernhard Rosenkraenzer 2001-05-14 06:36:27 EDT
Switching to NEEDINFO, please add which controller you're using.
Comment 4 Matthias Kruspe 2001-05-14 08:39:04 EDT
I am using the Adaptec AHA2940UW-Controler. The problem occures with the
original Red-Hat 7.1 Kernel from the Installation-CD. 
Harddisk is a IBM DDRS (SCSI-0)
ZIP Drive 100
(everything is SCSI)
Comment 5 Matthias Kruspe 2001-05-14 08:41:18 EDT
Maybe the type of the mainboard is interesting too.
It is a ASUS P2B (intel 440BX chipset)
Comment 6 Michael K. Johnson 2002-01-18 16:11:39 EST
I don't see what is happening here, but I'll ask the obvious question:
have you tried upgrading to our errata kernel?
Comment 7 Matthias Kruspe 2002-01-19 10:21:09 EST
I have upgraded. But I don't know whether it fixed the problem. I don't want to 
try it out again and risk my system.
