Kernel panic with ide-scsi emulation

[Daniel Betschart]

I have troubles to reactivate ide-scsi. I have changed my /etc/modules 
to load ide-scsi instead of ide-cd. I also load sg and sr-mod before 
ide-scsi. After that I load the driver for my SCSI adapter aic7xxx, 
because I have a MO drive also. In /boot/grub/menu.lst I have set 
hdc=ide-scsi hdd=ide-scsi.

After booting with recovery mode (no X) I see that ide-scsi is loaded, 
but also ide-cd. I unload ide-cd, mount a CD with mount -t iso9660 
/dev/hdc1 /cdrom and browse through the directories on the CD.

But when I want to copy the files to a location on the harddisk, the 
kernel becomes panic. The screen is full with messages about the stack.

I also receive a kernel panic if I do not copy files but unmount the CD 
and want to unload the module ide-scsi.
