[Bug 560717] [NEW] lucid sever fails to boot with LVM root

[Emmet Hikory]

Public bug reported:

When booting my powerpc server into lucid, it hangs in initramfs, unable
to find /dev/mapper/vg00-root : the same disk configuration and fstab
worked successfully under karmic.  To complete the boot, I must run the
following two commands manually:

modprobe dm_mod
lvm vgchange -a y

I do not encounter this issue on a similarly configured amd64 system.
Further investigation shows that the dm_mod kernel module is built-in
for amd64, and that the /dev/mapper/* nodes are populated correctly
during startup with this configuration.

Please set the dm_mod module to be a built-in also for powerpc (or any
other architectures where it may be missing).
