Affects: linux-meta linux-686 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
i got a strange problem with dappers actual kernel. my usb-disk isn't recognized/configured correctly (sdX), but as a generic scsi device (sgX). this is really strange:
- the same disk works in breezy without any problems. 
- a usb stick i also have works fine in dapper
- the disk doesn't work in firewire mode too.
