Subject2.4.17,2.4.18 ide-scsi+usb-storage+devfs Oops
The Oops happens after I use the ide-scsi module with my CDRW and then I
plug the Zip USB in.

To reproduce the oops:
1. Boot the machine (usbmgr should be started at boot)
2. rmod ide-cd ; rmmod ide-scsi ; rmmod sr_mod ; rmmod cdrom
3. modprobe ide-scsi
/dev/scsi/host2/bus0/target0/lun0/generic is created
4. modprobe sr_mod
/dev/scsi/host2/bus0/target0/lun0/cd is created
/dev/cdroms/cdrom0 -> /dev/scsi/host2/bus0/target0/lun0/cd
5. Plug the Zip in the USB
usb-storage is loaded
/dev/scsi/host2/bus0/target0/lun0/disc is created
/dev/scsi/host2/bus0/target0/lun0/part4 is created
/dev/scsi/host2/bus0/target0/lun0/cd disappears
/dev/cdroms/cdrom0 becomes broken link
/dev/scsi/host2/bus0/target0/lun0/generic changes from the CDRW
generic device to the Zip generic device
6. Unplug the Zip
/dev/scsi/host2/bus0/target0/lun0 disappears, I can only reach to
usb-storage is unloaded
7. different ways of provoking the Oops
7.1 umount /mnt/cdrom
7.2 rmmod sr_mod
7.3 rmmod ide-scsi
7.4 Any kind of trying to read or write the CD

The Oops does not happen if I unload ide-scsi, sr_mod, cdrom before
pluging the Zip in and if I unplug the Zip before modprobe ide-scsi and
modprobe sr_mod.
