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: Always Steps to Reproduce: 1.start ksysctrl 2.click refresh 3. Actual Results: heavy damage to the filesystem Expected Results: re-scanning the scsi-chain and refreshing the data shown Additional info:
*** 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.
