Installation was done using the Ubuntu LiveCD. Partitions on the filesystem was created beforehand using gparted. The partition table is set up to be GPT with a 8MB bios_grub partition, a 256MB fat32 EFIBoot partition (not used for this setup, board does not support EFI and is expected to boot from the bios_grub legacy partition), a 4GB swap, 80GB root partition, and the rest for /home. Then the installer is invoked and the partitions are set up. GRUB is told to install to the root of the RAID array in /dev/mapper . The installation went flawlessly. Upon reboot, GRUB loads as expected, and loads the kernel and initrd as expected. However, the kernel gives up on waiting for the root partition and drops to initramfs busybox. "dmesg|grep device" shows the following errors: device-mapper: table: 252:0: raid: unknown target type device-mapper: ioctl: error adding target to table Trying to invoke dmraid -a y results in the following error: ERROR: device-mapper target type "raid" is not in the kernel RAID set "nvidia_babddecf" was not activated. nvidia_babddecf is the assigned volume name by the controller.
