ksysctrl damages file systems when refreshing data

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)
Steps to Reproduce:
Actual Results: heavy damage to the filesystem
Expected Results: re-scanning the scsi-chain and refreshing the data shown
*** Bug 40451 has been marked as a duplicate of this bug. ***
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.
Switching to NEEDINFO, please add which controller you're using.
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)
CD-ROM is a PLEXTOR ULTRA-PLEX
ZIP Drive 100
(everything is SCSI)
Maybe the type of the mainboard is interesting too.
It is a ASUS P2B (intel 440BX chipset)
I don't see what is happening here, but I'll ask the obvious question:
have you tried upgrading to our errata kernel?
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.
