I'm having the same issue as being discussed in this thread with installation of a new Dell R610. i686 installation detects disks properly (output of lsmod attached). amd64 installation doesn't detect disks so I'm unable to install. Output seen in dmesg includes the line: mptbase: ioc0: Error - : ERROR - Unable to map adapter memory! I'm in the process of looking into this further but looks to me like the disk driver isn't being loaded properly for some reason. Note, this only seems to affect amd64. I've got a perfectly fine, working i686 installation and the i686 installer detects all disks and loads the module properly.
