Public bug reported:

Binary package hint: initramfs-tools

The Ubuntu version is 8.10 Server x86 (no updates, directly from the cd)
The hardware is Supermicro P3TDER with Promise TX4000 fake raid card.

I'm using software (md) raid, so *disable* SATA/fake raid during the
install. However on 1st boot of the newly installed system dmraid is
enabled - so it steals drives that the md arrays want to use, thus
making the system ubootable (/ is on a raid0 array). Note these cards
need you to define at least one fake array otherwise the BIOS cannot
boot the system (so having no fake arrays is unfortunately not
possible).

I worked around this by booting off the cd and choosing "rescue broken
system", then removing the dmraid package (possibly a bit clumsy, but it
worked).

I think the system should configure the boot ramfs to *not* use dmraid
if you have disabled it during the install.
