> When trying to install Ubuntu using LVM partitioning on top of a hardware
> RAID1 array, the kernel fails to be configured. The RAID1 array is
> recognized and activated by the device mapper (only when unnamed, see my
> other bug report: https://bugs.launchpad.net/bugs/367505). It appears,
> however, that mkinitramfs cannot find the root logical volume, and so it
> fails to produce the initrd. As mentioned above, this bug occurs only when
> using the expert mode of the installer. When using normal mode, the kernel
> installs cleanly even though the same LVM partitioning scheme is used.

> I have attached the end of the syslog, which shows the erros mentioned
