Bug Description
This is known to affect the Ubuntu Server Daily Build of Ubuntu 12.04, as of March 21, 2012.
The kernel modules for 'dm-mirror' and 'dm-raid' are missing from the Ubuntu Server x86_64 CDROM's initrd, which prevent the installer's dmraid setup from starting (for example NVidia and Silicon Image ATA fakeraid controllers that are set up for mirrored operation).
No error is reported to user that the dmraid was not properly initialized - it silently fails, and presents the individual drives of the mirror for partitioning.
Compounding this issue, for upgrades of systems that are running lvm2 on top of dmraid mirrors, the lvm2 'vgchange -a y' *does* occur, which then leads the installer to perform the installation on only half of the drives in the raid set (assuming that they are in the LVM volume groups).
Again, no error or warning is presented to the user.
Curiously, at least on the Silicon Image software raid, this does not break the raid set and start a rebuild.
If dmraid is later installed on the system, the newly generated system's initrd will allow the raid to come up in a very strange, broken manner that rapidly leads to filesystem corruption, and an unusable installation.
Also: bug data attached to this report is from another system, that does not have this issue (no dmraid). Also, is 'debian-installer' the correct package to use when reporting problems with the ISO installer and initrd?

I am also experiencing this issue while trying to install Ubuntu 12.04 on Intel DH67BL motherboard with RAID-1 configuration.
I have tried several different versions and builds of Ubuntu 12.04 and they all suffer from this issue: 12.04-alpha2- server- amd64.iso 12.04-beta1- server- amd64.iso server- amd64.iso @ 2012-03-20 server- amd64.iso @ 2012-03-22

In all cases installer does not report any problems, but syslog contains the following:
disk-detect: ERROR: device-mapper: target type "mirror" is not in the kernel
